Huh ... gaur did this:
/usr/ccs/bin/ld: Unsatisfied symbols:
sigwait (code)
which is not what I was expecting, because there is a definition for
sigwait in /usr/include (though not in a header file we use). It must
be in some add-on library instead of libc.
However, wrasse did this:
"/export/home/nm/farm/studio64v12_6/HEAD/pgsql.build/../pgsql/src/bin/psql/command.c", line 5062: prototype mismatch: 2
argspassed, 1 expected
cc: acomp failed for /export/home/nm/farm/studio64v12_6/HEAD/pgsql.build/../pgsql/src/bin/psql/command.c
which I was expecting even less. Evidently, prehistoric HPUX is not the
only platform still using the pre-POSIX API for this function. So we
really do need the full configure check.
