I can't confirm whether this problem exists or is a regression, but if it does
then it's a fixincludes bug since fixincludes (fix solaris_complex) is supposed
to make the system complex.h header suitable for GCC.

Can you see if fixincluded complex.h is used, or for some reason the system one
instead?  If the former, can you diff up the system one and the fixincluded
one?
You can run gcc -E foo.c | grep complex.h to see which complex.h is being used.

Clearly the system complex.h is being used, does that mean that the header
hasn't been fixincluded at all?  The diff is against a wrong header, you are
diffing system complex.h against C++.
Can you look into your logs if you have message like:
Applying solaris_complex          to complex.h
in your build log?  Can you look into your build tree if you have
gcc/include-fixed/complex.h
header?  Did it get installed?
/usr/local/gcc-4.6.0/x86_64-SunOS-core2/lib/gcc/i386-pc-solaris2.10/4.6.0/include-fixed/complex.h
would be the installed location of the file.

i386-pc-solaris2.10 is neither primary nor secondary target.  And we are
still waiting for answers.
