I've been building libxml2-2.7.8 and have been having a heck of

I've finally confirmed that the issue is caused by optimizations
with -O2 or -O1. If I use -O0 the issue goes away. The effect is
the xmlIsPubidChar_tab array is seen by xmlcatalog to contain all
0x00 values. I'm using GCC-4.6.1 and binutils-
as delivered by MinGW. I wanted give this list a report of what
I've found in the event others come by, they may have already.
hmm ,

Look like regression as it is fine with me for gcc/binutils: -
3.4.5/2.17.50 20070129 - 4.4.0/2.19.1

It was Kai Tietz who is active in GCC development for Windows and one of
its maintainers who pointed me to the issue resolution.

See for the
Above like is fine to follow the thread .
I'm not against the patch
a) it will resolve linking issue if libxml2 is build with gcc (mingw) and -nocommon flag.
b) it will resolve issue with new gnu compiler/linker
c) libxslt and xmlsec for instance use extern for mingw* compilers

Lets first finish discussion on mingw list as libxml and libxslt does not use extern for cygwin compiler. If cygwin build is impacted then complete patch must cover both woe compilers. Also another patch for libxslt is required .
