[vlc-devel] Extras/contrib libxml broken under Cygwin

[Mark Moriarty]

Latest Cygwin environment, freshly updated.

When in extras/contrib, SVN Update returns: At revision 16518.

Trying to do a "make src" in extras/contrib, I've tried kill-and-fill on the
XML subdirectory, to make sure it wasn't a botched download.

I keep seeing:

		Start of the make for libxml...
Making all in libxml
make[5]: Entering directory
`/home/mfm/vlc-trunk/extras/contrib/src/xml/include/
libxml'
		I get multiple warnings during the make, of the form:
cc1: warning: -Wuninitialized is not supported without -O
		I also get:
encoding.c:3023: warning: string length `688' is greater than the length
`509' I
SO C89 compilers are required to support
encoding.c:3133: warning: string length `624' is greater than the length
