I don't know much about porting/compiling, so I can't assess it. My
code does not really depend on gcc afaik. The generated C is not that
complex. What are the differences between gcc and other compilers I
should take care for? Command line syntax? Is cython's C gcc-
dependant?
We could include gcc (2.7 MB) and cython (1.2 MB) in sympy optionally
(kind of add-on). It's a smaller dependancy than Python. sympy can
easily fall back to Python lambda if necessary.
I care about POSIX and Windows (only due to its spread), other OSes
are nice to have, but not a must. After all, I don't have access to
any other so far. How many sympy users do not use either Windows or
Linux?

As said before, we could include gcc at least for Windows. But Windows
support will wait until cython is fixed (afaik ':' and '\' are not
allowed in variable names).
After all, the feature is not critical. Users of exotic OSes can
dispend with it.
Psyco for example is even more platform-dependant and though popular.
