What do you think?
It's the same compiler, other than a very tiny amount of OS-specific code. The "config" subdirectory isolates OS-specific code; if you want details, you could check out the files in that directory beginning with "sol2". (If you aren't prepared to dive into the source you're probably on the wrong list and might find gcc-help more appropriate, this is the development list for the compiler itself). It seems that the biggest differences are: * wchar_t and wint_t are different; * support for either the Sun or GNU linkers; * support for Solaris pragmas.
