Re: [avr-gcc-list] Trouble compiling avr-gcc > 4.4.4 on Mac OS X Leopard with gcc-4.2

[Mark Salyzyn]

I have been using 4.6.1 and built no problem under MAC OSX 10.5.8 on  
Intel. And am using the apple compiler (4.0.1) to build?

mpfr, binutils, gmp are all 'in-tree' for the builds and are all soft  
links to the source trees like you have. No patches, but some small  
manual work merging libiberty of gcc and binutils together (Makefile.in)

mpfr 3.0.1
gmp 5.0.2
gcc 4.6.1
binutils 2.21.1

Editorial Comment: I ran a peephole-optimizer on the assembler output  
of this compiler-suite and managed 0.2% smaller code, better than  
past, but still some silly compiler output here and there none-the-less.

Sincerely -- Mark Salyzyn
