For starters, the Singular developers don't work with those compilers,
so the Singular devs will make all kinds of code changes, which would
then have to be ported/fixed.
As has been discussed previously, this effort is worthwhile in any
case. Firstly, gcc does not generate especially good SPARCv9 or iA64
code - being able to use vendor compilers is likely to provide a boost
to Sage performance on those platforms. Secondly, the different checks
performed by different compilers are likely to turn up in Sage code and
correcting them will improve the reliability and robustness of Sage.
I agree with this very much. I think William see evidence of how the Sun
compiler (which was being called by mistake), found two serious bugs in c_lib.

Unfortunately, so much of the code in Sage is written in a GNU dialect of C/C++
and not C/C++, that building Sage with native compilers would be very difficult.
Even getting the compilers to be called is difficult, as so many bits of Sage
ignore $CC, $CXX etc.
Here's just a few I can bugs I can quickly find - I rather gave up collecting a
list of them, there are just so many
