I just did that and then I tried to replace the occurrence of longjmp 
within png.h with siglongjmp - don't ask why ;)
That work's.... it compiles cleanly. It passes the simple tests (but bus 
errors with the full test...) somehow png.h is able to make longjmp 
disappear...

It also works ok for NetSurf, but netsurf has __STRICT_ANSI__ + 
__USE_BSD (somehow, somewhere, maybe not even intentionally) which 
results in no declaration of siglongjmp ... ( but that is used within 
the png.h that is also included by NetSurf)

So I patched NetSurf a little:
#ifdef __STRICT_ANSI__
#undef __STRICT_ANSI__
#include <setjmp.h>
#define __STRICT_ANSI__
#endif

It work's, but somehow I think that people want to be able to use libpng 
with the usual longjmp....

To be honest I don't understand what is the problem, I just see that 
png.h is able to make longjmp disappear, but siglongjmp is still around...

So, it looks like I will build an 1.2.40 rpm...
