user must install mathlib.prc

well, if mathlib.prc is < 64k, you *could* look for it,
and, when finding it fails - install a copy of it using
DmCreateDatabaseFromImage :)

you can find these routines yourself using simple series
analysis. any good math book will give you a simply way 
to implement these functions.

mathlib.[ch] are only there to allow you access to the
mathlib.prc functionality. dont expect to actually include
mathlib itself just because you use the .c and .h files.
