Thread: posgresql 7.3beta3 compile error in src/pl/plperl (perl extension)

Hi.

I've got a compile-time error when trying to build postgresql 7.3beta3 with
perl:

./configure --with-perl
make

It's linux 2.4 on pentium III, gcc 2.95.3, glibc 2.2, perl 5.8 (with support
for large integers (long long, 8 byte)).

This is a bug in Perl 5.8.0. To workaround it, add '-D_GNU_SOURCE' to
the CFLAGS for PL/Perl.

I'm planning to send in a patch that works around this problem for 7.3
final, but I haven't got a chance yet (if someone feels like doing it,
go right ahead).

Cheers,

Neil
