[Sdcc-user] Some patches

[Wim L. <wi...@us...>]

I've put a couple of patches on sourceforge which fix problems I've seen
with the current cvs version of sdcc. Patch #608752 applies to the
target-independent part of the compiler and avoids a problem with
read-modify-write operators (e.g. foo += bar) when the left hand side has
complicated side effects. Patch #609842 fixes a handful of problems with
the 8051 register allocator and code generator, mostly places where the
register-packing code was being over-eager.
