Summary:
In Microsoft C versions 5.0, 5.1, 6.0, 6.0a, and 6.0ax, the Microsoft
run-time library math routines are nonnreentrant and accordingly do
not save and restore the registers used on the 80x87 floating-point
coprocessor.
If you want to develop a program that requires the math coprocessor to
be reentrant, you must provide your own routines that save and restore
the registers of the coprocessor.
