- move the pkgsrc related HACKS into a separate file.
- remove the pkgsrc|basesrc|syssrc (etc) prefix from file entries;
it wasn't consistently used anyway

It needs + some symbols from libgcc.a, such as __eh_alloc. It's not possible + to link the xerces-P shared object with libgcc.a, because libgcc.a + is not compiled with -fPIC. Hence we need to have the missing + symbols in the Perl executable. + This hack includes the whole libgcc.a in the Perl executable, and + links with c++ so that some mandatory symbols such as __pure_virtual + are also included. It should go away with GCC-3.0, or if we make a + libgcc.so on day. +kcah + +hack gcc-2.95.3 -O* bug +mdate 12 Feb 2002 +who mrauch +port i386 +file devel/pth/Makefile : 1.37 : 20 : 22 +descr + OpenOffice segfaults after some time in the pthread library with a + completely thrashed stack.
