I think this bug can be closed only when 3.4 gets released since it will be the first gcc 
which requires an ANSI/ISO C compiler.

Could you please clarify this report?  We need to know what the errors in bootstrap are with the optional *ANSI* compiler.  The errors with the 
"bundled" compiler are not going to get fixed, and for 3.4 we'll require the ANSI compiler.  But errors bootstrapping with the ANSI compiler, we 
have to fix.

The problem looks like the submitter didn't use make bootstrap, hence fastjar is
picking up the wrong compiler, and failing.

Hello,

I rechecked, using gcc 3.3. [I changed the version number in the
report accordingly]

These are my findings on HPUX 10.20, using HPs ANSI-C for bootstrapping.
I configured as advised in a separate directory using
export CFLAGS="+DAportable -Ae +O2"
../gcc-3.3/configure -prefix=/pd/gcc3.3 --without-gcc --with-gnu-as --with-
as=/pd/binutils/bin/as --without-gnu-ld --with-local-prefix=/pd/gcc3.3/include -
-enable-languages="c, c++"


First I get some errors from configure:

checking assembler --gstabs support... yes
checking linker read-only and read-write section mixing... conftest1.s: 
Assembler messages:
conftest1.s:1: Warning: rest of line ignored; first ignored character is `"'
conftest2.s: Assembler messages:
conftest2.s:1: Warning: rest of line ignored; first ignored character is `"'
conftest2.s:2: Warning: rest of line ignored; first ignored character is `1'
conftest3.s: Assembler messages:
conftest3.s:1: Warning: rest of line ignored; first ignored character is `"'
conftest3.s:2: Warning: rest of line ignored; first ignored character is `0'
/usr/ccs/bin/ld: (Warning) Can't hide symbol "ared"
/usr/ccs/bin/ld: No $UNWIND_END$ subspace has been defined (probably 
missing /usr/ccs/lib/crt0.o)
unknown
checking linker PT_GNU_EH_FRAME support... no
------------------------------------------
I didn't try to track those down. Suggestions ?

Then I do "make bootstrap"
This yields:
[...]
cc -Wp,-H256000 -c   -g  -DIN_GCC     -DHAVE_CONFIG_H    -I. -I. -I../../gcc-
3.3/gcc -I../../gcc-3.3/gcc/. -I../../gcc-3.3/gcc/config -I../../gcc-
3.3/gcc/../include ../../gcc-3.3/gcc/ggc-page.c -o ggc-page.o
cc: "../../gcc-3.3/gcc/ggc-page.c", line 191: error 1709: Long double is an 
ANSI feature.
gmake[2]: *** [ggc-page.o] Error 1

This  is caused  by '-Ae"  (In  the CFLAGS  env-var during  configure)
not showing up in the compiler-flags.
Adding -Ae to STAGE1_CFLAGS in gcc/Makefile solves this problem.

Funnily enough, if I look at some compiles sooner during the build, I find -Ae, 
e.g.:
cc -Wp,-H256000 -c -DHAVE_CONFIG_H +DAportable -Ae +O2 -I. -I../../gcc-
3.3/libiberty/../include   ../../gcc-3.3/libiberty/dyn-string.c -o dyn-string.o

But adding -Ae to the CFLAGS in Top-level-Makefile will "make
bootstrap" fail for later stages !
(configure fails, because "compiler can't produce executable !")

So later on I have to remove it again and do a new 'make bootstrap'.
Is there a "correct" way to supply the flags specific to the stage-1
compiler to configure, so they get propagated correctly ?

Other than that the compile and link was successful.

I'm still fighting with tha java-part. (and thus fastjar). I will
update the report, as soon as I get reasonable results.

BTW:
I got some problems when trying to _use_ the resulting g++/stdlib. It
gets upset about missing ios_base::streamoff.
I found PR 7219, which suggest to rebuild with
CXXFLAGS='-D_GLIBCPP_DEPRECATED'. This solved the problem.
Could configure please add this if it finds gcc being compiled on and
for HPUX 10.20 ?!

STAGE1_CFLAGS will be passed down if it's defined in the environment at the top level.

Hopefully, if I ever manage to move bootstrap to the top level, that whole issue will vanish. :-/

The C++ deprecation issue means that whatever you're building which uses the
deprecated stuff should be updated to *not* use the deprecated stuff; it's not
HPUX-specific.

1) fastjar problem: don't build java.  Java is not supported on any PA
   port at this time.  This is because we don't have a libffi port.
   Use `--enable-languages=' to explicitly specify the set of languages
   to build.

   As of 3.4, support for building GCC with a non ANSI compiler has been
   dropped.  Thus, it will no longer be possible to build GCC 3.4 and
   later with the bundled HP C compiler.  However, fastjar requires an
   ANSI compiler to build even in earlier versions of GCC.

2) CFLAGS: don't try to use CFLAGS to specify compiler options (e.g.,
   CFLAGS="+DAportable -Ae +O2").  A better way is to use CC (e.g.,
   CC="cc +DAportable -Ae").  This is the preferred technique as the
   config.guess script uses CC for its guess.  You can also use
   STAGE1_FLAGS to set the CFLAGS for stage1 of the bootstrap.

There is nothing new in this bug, every thing is documented in the manual.  Also no 
feedback in 2 months.
