A couple of small fixes to get things working on solaris.

added #include <ieeefp.h> similar to where its included in
other files. (made an ifdef that matches other includes of the same
file)

solaris does a lot of type overloading so there is no expf its just exp
so I added a #define expf exp wrapped in an ifndef

Finally, I fixed a warning in cfglexer.cpp about multiply defined
yy_wrap functions.
