Well, more precisely, it is dependent on functions in the recent
X/Open Unix standard.
These dependencies seem to be:
* The inclusion of <wchar.h> to get the functions wcslen, wcscpy
and wcncpy. These seem to be present in <wcstr.h> on some machines
(could people who are having problems check?) -DX_LOCALE could
also be forced in the absence of wchar.h, since these functions
can be gotten from the X library.
On the other hand, they currently aren't used anywhere anyways...
(as evinced in by the typo in the line:
#define wcsncpy(a,b,c) _Xwcsnpy ((a),(b),(c))
* The use of iswalnum() in gtkentry.c.
This is a more fundamental problem as it isn't included in the
X libraries. (So it won't work properly with -DX_LOCALE in effect
even if your libc has it!) But I'll add something like
HAS_WCTYPE_H to remove the compilation problems.

Looks like a good workaround.
