AFAIK there's no way to find out which compiler was used to build
PostgreSQL binaries (IIRC this is not in pg_config). So you can do this
gcc --version
That should print version of the default compiler, and it's very likely it
was used to build the PostgreSQL binaries. If it's 4.6.0, you've been hit
by the problem Fujii Masao described. Use a different gcc version and it
should work fine.
