We got it to build fine on both Suse and RHAS, but have had no luck with
VAC.

That is we were able to compile it using GCC, but not VAC

I have not researched any deeper,but currently it fails with

.[hannu@power postgresql-8.0.3]$
CC=/opt/ibmcmp/vac/7.0/bin/xlc ./configure
..A..
checking for int timezone... yes
checking types of arguments for accept()... configure: error: could not
determine argument types

Our "supported platforms" page does not show compiler, perhaps it should
be there as a separate column, not as remark for just some platforms.

So look at config.log and see what's going on.

The odds are very high, that it rather depends on the system header file version,
or the order of inclusion (e.g. stdio.h before config.h).
Would need to see the snippet of configure output though.
IIRC there was a fix for this or a similar case, has this been reverted ?

the following is repeated several times:

------8<--------8<--------8<--------8<--------8<--------8<--------8<--------8<--
configure:11574: /opt/ibmcmp/vac/7.0/bin/xlc -c -O -D_GNU_SOURCE conftest.c >&5

#endif

{

;
return 0;
}
------8<--------8<--------8<--------8<--------8<--------8<--------8<--------8<--

and then end looks like this

------8<--------8<--------8<--------8<--------8<--------8<--------8<--------8<--
#define HAVE_STRUCT_SOCKADDR_STORAGE_SS_FAMILY 1
#define HAVE_STRUCT_ADDRINFO 1

it needs this:

extern int accept (int __fd, __SOCKADDR_ARG __addr,
socklen_t *__restrict __addr_len);

how does one add yet another set of arguments for accept() to
configure ?

One patches the file config/ac_func_accept_argtypes.m4. Presumably, you
need to add another choice to the loop for ac_cv_func_accept_arg2.
