Bootstrap failure on AIX4, alloca missing, (main trunk only)

Bootstrap failure on AIX4, alloca missing, (main trunk only)

[Kaveh R. Ghazi]

	I'm having a strange problem bootstrapping gcc-2.96 19990607
on powerpc-ibm-aix4.1.4.0.  It occurs when I use cc for stage1.

 > cc -DIN_GCC -DHAIFA -g -DHAVE_CONFIG_H -o cccp cccp.o cexp.o intl.o
 > 	prefix.o version.o mbchar.o obstack.o ../libiberty/libiberty.a
 > ld: 0711-317 ERROR: Undefined symbol: .alloca
 > ld: 0711-345 Use the -bloadmap or -bnoquiet option to obtain more
 > 	information.
 > make[2]: *** [cccp] Error 8

	Normally x-aix41 tells gcc to link with alloca.o, but it
hasn't worked for a couple of weeks.  I did some investigation and it
appears that x-aix41 is no longer inserted into the Makefile at all.
(E.g. if you link with alloca.o by hand everywhere, there are other
problems caused by x-aix41 not being used.)  I think this started
happening after the following patch was installed.  I can't tell why
the patch would cause this to happen though.  (I.e. the patch looks
perfectly fine.)

	Note this patch, and thus the problem itself, only occurs on
the trunk, not on the 2.95 branch.

So you ask: why didn't the link get alloca.o from libiberty.a? :-)
Well that's because AC_FUNC_ALLOCA determines that AIX4 does have
alloca because the test utilizes "#pragma alloca", but we don't issue
that pragma or do any other alloca handling in the sources other than
in the x-* files.  I don't know if we want to change that, but it did
throw me a puzzle... :-)

	Anyway, if someone familiar with the $xmake_file handling in
configure.in could give me some tips I'd appreciate it.  Otherwise,
I'll try to figure it out myself.

The following error occurs in gcc-2.95 19990608:

make[3]: Entering directory `/xxx/gnu/gcc-2.95/objdir/gcc/fixinc'
autogen -DPROGRAM=1 -b fixincl inclhack.def

make[3]: Leaving directory `/xxx/gnu/gcc-2.95/objdir/gcc/fixinc'
Could not install binary fixincludes.
Installing shell script instead.

I guess I need to update autogen to version 4.5.3 to evaluate this
expression.  However, this is non trivial under hpux for a variety
of reasons.

Yes. You need a newer version of autogen.

The problem is a typo in my patch.  I checked in the following patch to fix
it.

	Grr, I must have stared at it a thousand times without
noticing that typo. :-)  Thanks Jim.
