Quick hack to get this file compiling again on Mac OS X. The right thing to do
...
is write an autoconf macro that checks whether __isnan or isnan actually works
**using the C++ compiler after #include <cmath>**, instead of doing it the easy
way with AC_CHECK_FUNCS().

Restructure call constant folding code a bit to make it simpler
...
Add support for acos/asin/atan. 188.ammp contains three calls to acos with
constant arguments. Constant folding it allows elimination of those 3 calls
and three FP divisions of the results.
