testing for usable C compiler

BTW, would it be possible to tweak configure's test for "minimum working
C compiler" to include a check that cc accepts ANSI-style function
prototypes? That would allow us to bounce HP's lame excuse for a free
compiler with a slightly useful message ...

configure:10847: cc -Ae -c +O2 -D_XOPEN_SOURCE_EXTENDED conftest.c >&5
(Bundled) cc: warning 480: The -A option is available only with the C/ANSI C product; ignored.

Get a real compiler :-(

The "bundled" cc is a piece of junk that HP ought to be ashamed to ship.
You cannot build Postgres (or much of anything else) with it. If you
don't want to shell out for HP's real C compiler, install gcc.
