Sage error.

The following function templates are in stdlib.h that exists in
/usr/local/lib/gnu/lib/gcc-lib/alpha-dec-osf3.2/2.7.2/include. This file is
included in a benchmark program that performs continued fraction factoring. I am
executing sagecc after pre-processing the program with gcc. sagecc gives the
appended error for these function templates.

size_t		wcstombs( char *__s, const wchar_t *__pwcs, size_t __n );
int		wctomb( char *__s, wchar_t __wchar);
