[avr-libc-dev] -mint8 problem with setjmp/longjmp

[Nils Kristian Strom]

Hi

Looking at the setjmp.h header, I noticed the use of unsigned int in stead of
void * for all addresses.  The following patch seems to fix this problem.

Note that for devices with >128K FLASH I don't know if sizeof(void *) would be
2 or 3, this may be wrong in the patch.

Regards
