[xml] undefined reference to 'open'

I'm trying to integrate libxml Library to my current Project: - PowerPC MPC852 - GCC crosscompiler, cygwin, powerpc-linux 2.95.2 I'm getting the following build error: 1Lib/libc.a(openr.o): In function `_open_r': 1/home/Administrator/newlib-1.8.0/powerpc-linux/nof/newlib/libc/reent/openr.c:58:

[xml] libxml: disable file handling functionality?

I'd like to use the libxml library without file handling (just reading and parsing XML data from memory). Because of the file access functionionality of libxml (function 'open') I've got a problem to build the library (have a look to thread 'undefined reference to 'open' in the mailing list).
