I'm trying to build the gpc-20040516 "beta" snapshopt with GCC-3.3.x on AIX 5.1. GCC-3.x itself supports AIX 5, I have a working version on the system (binary install, not compiled-it-myself).
I tried gcc-3.3.3 and gcc-3.3.1, and followed the INSTALL instructions, using a separate build directory, configuring with
/gnulocal/src/gpc-build> /gnulocal/src/gcc-3.3.x/configure --enable-languages=pascal --prefix=/gnulocal
which went well, including patching the respective compiler (tried with 3.3.3 and 3.3.1).
Then running "make" with no arguments:
/gnulocal/src/gpc-build> make
make works for quite a while, and then fails in compiling /gnulocal/src/gcc-3.3.1/gcc/p/lang.c with the following messages:

the line 511 is this one:
TARGET_CPU_CPP_BUILTINS ();...which fully escapes me as for why it might not compile...!??
The problem is that the backend on this target uses some functions from the C frontend (wrongly) via TARGET_CPU_CPP_BUILTINS.
Unless you need very particular system conditionals (Pascal programs usually don't), just insert the line
#define rs6000_cpu_cpp_builtins(foo)
in lang.c.
