>Description:
I originally attempted to build the C and C++ compiler on 10.20, but due to the following problems and insufficient disk space, I finally built just the C compiler.  There are three problems I noted with what I did try:

1.  When building the C compiler, the STAGE1_CFLAGS was 
    not being overridden with the value of CFLAGS, and 
    the compilation would fail:

    Build cmd: gmake CFLAGS='-O -Ae' LIBCFLAGS='-g -O' \
               bootstrap

    Snippet of error (linefeeds added for clarity):

    gmake[1]: *** [stage1_build] Error 2
   
    If I changed STAGE1_CFLAGS to match the value specified
    for CFLAGS (i.e., to specify an extended ANSI 
    compilation), the build would complete.

2.  If building both the C and C++ compiler, setting
    STAGE1_CFLAGS for extended ANSI compilation caused 
    the compilation to fail at a later stage:

    Build cmd: gmake CFLAGS='-O -Ae' LIBCFLAGS='-g -O' \
               LIBCXXFLAGS='-g -O -fno-implicit-templates' \
               bootstrap-lean

               Note:  gcc/Makefile was edited to set
               STAGE1_CFLAGS to "-O -Ae" due to problem #1.

    Snippet of error (linefeeds added for clarity):
    checking for BSD-compatible nm... /usr/ccs/bin/nm
    checking how to recognise dependant libraries... 
       file_magic (s[0-9][0-9][0-9]|PA-RISC[0-9].[0-9]) 
       shared library
    checking for object suffix... configure: 
       error: installation or configuration problem; 
       compiler does not work
    gmake[1]: *** [configure-target-libstdc++-v3] Error 1

  gcc-objdir/hppa1.1-hp-hpux10.20/libstdc++v3/configure/log:

    configure:2143: /usr/gcc-objdir/gcc/xgcc 
       -B/usr/gcc-objdir/gcc/ 
       -B/usr/local/hppa1.1-hp-hpux10.20/bin/ 
       -B/usr/local/hppa1.1-hp-hpux10.20/lib/ 
       -isystem /usr/local/hppa1.1-hp-hpux10.20/include 
       -c -O -Ae  conftest.c 1>&5
    <command line>:1:2: missing '(' after predicate

    The error refers to the "-0 -Ae" options.  If I
    manually edit the Makefile to set STAGE1_CFLAGS 
    back to its original value, the make would continue
    and I would not see this error.

3.  When building the C and C++ compiler, I used the
    "bootstrap-lean" option as I have very little disk space
    to work with.  I'm not positive, but I believe this 
    was what caused my following link error.  I did not get
    this error when I built just the C compiler specifying
    "bootstrap" instead of "bootstrap-lean".

    Build cmd: gmake CFLAGS='-O -Ae' LIBCFLAGS='-g -O' \
               LIBCXXFLAGS='-g -O -fno-implicit-templates' \
               bootstrap-lean

I was finally able to build just the C compiler, but it would not generate symbol tables when I compile a file using gcc and the -g option.  I have not determined why this is so, and have left that problem for another day!
>How-To-Repeat:
The gmake options and steps taken are noted above in "description".
>Fix:
I apologize, but I have none to offer ... I was so frustrated with my lack of disk space and limited ability to print files, that I did not attempt to resolve the problem.
