This is not about duplication of efforts in Sage. My point was to
illustrate that the assumption "C compiler == gcc" does not hold. And
even with gcc you might run into trouble on other platforms. One
example: While the Sun Forte cc does define log2 in math.h the math.h
provided by Solaris 9 and the system does not. Hence if you use log2
with gcc on Solaris it will not work. This seems to be a minor issue
in your case, but from experience porting software is hard. Not
writing code hardwired for one toolchain is worth it from my
experience.
And most people on Windows do not even have a compiler installed. It
might be different for the people that Sympy appeals to, but I would
assume that the ratio of developers to users on Windows probably much
worst for Sympy to the ration on Linux.
