Joel's Only Outstanding RTEMS Newlib Patch
Wed Dec 16 21:55:00 GMT 2009
A while back I submitted a patch to use sizeof(double)-1
for ALIGNBYTES to avoid an unaligned access on SPARC.
param.h in BSD is target specific and this made it safe
but larger than necessary. The attached patch makes
if "sizeof(double)-1" for SPARC and retains the old
value of "sizeof(int) - 1" for other targets.
Our machine/param.h came from i386 so it isn't that surprising
that it turned up an issue on a RISC CPU. It just took a long
time and "ls" ported from BSD. :)

for ALIGNBYTES on SPARC.
