fpmath.h is in libc and needs a couple of -I paths to reach.

local.h just declares everything theat might not be in math.h.  Attached.

You will have to fake log*l() or not compile clogl().

I don't like the combinatoral explosion in the number of interfaces,
but wanted to keep local.h readable.  cplex.c uses macros to avoid
repetition, but this is painful for debugging compared with a previous
version.
