works, but for example C<bin:perl -v> doesn't. The exact reason isn't
known but the current suspect is the F<ixemul> library.
-=head2 mod_perl 1.26 Doesn't Build With -D_GNU_SOURCE
-
-In Linux, building mod_perl with B<threaded> Perl 5.8.0 does not work
-because starting from 5.8.0 building a threaded Perl uses the
--D_GNU_SOURCE flag. The Apache 1.3.23 sources that are built
-alongside mod_perl don't like that flag and the compilation dies
-because of function prototype conflicts. This may or may not get
-fixed in later releases of mod_perl than the current 1.26 or in later
-releases of Apache than the current 1.3.23 (fixing the problem in Perl
-is less likely since threaded Perl in Linux now needs the -D_GNU_SOURCE>).
-Workarounds include using non-threaded Perl and using Apache 2.0.
-An obvious workaround would be to stop the -D_GNU_SOURCE from reaching
-the Apache 1.3.23 sources, but as of Perl 5.8.0, the complex build
-system of mod_perl has foiled this idea.
