That would be great.
BTW, I never heard any complaints about XView's varargs usage on ppc back
in the glibc 2.0 days (but then, I don't know wheter somebody actually
compiled it for ppc at that time). However, for glibc 2.1, somebody
submitted a patch that changed the following in lib/libxview/attr/attr.c:94
and a few other places:
#if (__GLIBC__ > 2) || (__GLIBC__ == 2 && __GLIBC_MINOR__ >= 1)
__va_copy(valist, valist1);
__va_copy(avlist, avlist1);
#else
valist = valist1;
avlist = avlist1;
#endif
If I look at the definition of __va_copy, it's
#define __va_copy(dest, src) (dest) = (src)
on all platforms except ppc, where it is
#define __va_copy(dest, src) *(dest) = *(src)
Is ppc varargs really that different from the rest of the world's, or could
this be a bug in gcc's header files?
