Unable to build gcc on AIX 5.3

Unable to build gcc on AIX 5.3

I am getting the following errors:

Stop.

Stop.

I have seen postings about the setset64_t errors, and they mention the
-npowerpc compiler flag, but since I am not able to build the compiler,
that info does not help.

Thanks.

[Ferng, Andrew D]

http://aixpdslib.seas.ucla.edu/packages/gcc.html 

I used the binaries from UCLA and it worked well so you might want to
try that if you don't need any special compile options.

	The problem is that you are trying to run GCC built for AIX 4.3.2
(note the powerpc-ibm-aix4.3.2.0 in the path) on AIX 5.3.  GCC uses cached
copies of header files that it "fixes".  If there is no change, no header
file is cached.  This causes a sequence of included header files to thread
between GCC's copy and the system header files.  Different releases of AIX
change the header files in ways that one cannot mix them.

	To bootstrap a newer version of GCC on a newer release of AIX, the
solution is to delete the GCC header file cache FOR THE SOLE PURPOSE OF
BUILDING GCC.  Do not use GCC in that state for any other purpose than
building and immediately installing the new version of GCC.  Do not
complain to me or anyone else if that warning is ignored.
