Non-GCC Cross Compilers?

Asmodeus asks: "Does anyone know of a commerical or commerically supported C++ cross compiler which is not GCC and which will target the complete gaumet of Enterprise platforms (including Win 32 DLLs). It must be hosted on Solaris and Windows NT/2K. GCC won't cut the mustard due to buggy sparc-64 bit support (incomplete target floating point implementation on host side) and the recent stability problems with 2.95+ have gotten people here a little nervous. I am currently not interested in compiling for embedded systems, only Enterprise grade platforms (and Win 32). The compiler must support shared library compilation for all target platforms, and ideally have a good debugger for all platforms. I've looked around at a lot of the compilers out there and it looks as if this is an area not many companies are interested in. [Note to GCC manics - I use it and I think it's great, but we have reached the limits of its capabilities..] Any suggestions greatfully received!"
