Patch to compile gcc-4.3.1 on Solaris 9 with Sun Studio 11

[David Diffenbaugh <davediff at jla dot rutgers dot edu>]

When trying to compile gcc-4.3.1 using Sun Studio 11 on Solaris 9 I 
received the following compilation errors for fixed-value.c and 
tree-ssa-loop-ivopts.c:

cc -c   -g -DIN_GCC     -DHAVE_CONFIG_H -I. -I. -I../../gcc-4.3.1/gcc

and

In both cases this seems to be occurring because Sun Studio 11 does not 
like the types of the operands in the conditional expression. I wrote a 
patch which just converts the conditional expression to the equivalent 
if/else block with assignment statements. The compiler had no complaints 
about this. I have posted this bug as 
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=37122
but it seems that this is possibly a bug in Sun Studio 11. The patches are 
attached for anyone with the same issues. I will also be sending this 
issue to Sun.
