On a RHL 8.0 box, I'm getting this:
gcc -O2 -g -fpic -I. -I/usr/lib/perl5/5.8.0/i386-linux-thread-multi/CORE -I../../../src/include -c -o plperl.o
plperl.c
In file included from /usr/lib/perl5/5.8.0/i386-linux-thread-multi/CORE/op.h:480, from
/usr/lib/perl5/5.8.0/i386-linux-thread-multi/CORE/perl.h:2209, from plperl.c:61:

/usr/lib/perl5/5.8.0/i386-linux-thread-multi/CORE/reentr.h:747: confused by earlier errors, bailing out
make: *** [plperl.o] Error 1
Is anyone else seeing the same? I'm confused because I'm quite sure
it built there recently. I suspect one of the recent changes to our
configure stuff broke it, but I don't see the connection offhand.
A little bit of digging suggests that this Perl include file will
compile as-is if and only if _GNU_SOURCE is #define'd (that's the only
way to get <crypt.h> to define the needed struct). Now Perl's config.h
does define that symbol --- but far too late, because it has to have
been defined the *first* time <features.h> is read, or it won't have any
effect. So I don't see right now how this could ever have worked.
But it did, and not too long ago. Any ideas?
