Re: [pgsql-patches] Patch to avoid gprofprofilingoverwrites

OK, I took Korry's gmon.out patch and Nikhil's configure.in patch and
made a combined version. It seems the gmon.out and -pg flags are
GCC-specific, rather than being platform-specific, so what I did was to
allow --enable-profiling to only work with GCC.

Patch attached.
