Name            _initfmode - initialize pointers to math error handlers

Usage           void _initfmode(int *fmodeptr);

Prototype in    none

Description     This function initializes _fmodeptr to point to the user
                EXE's _fmode variable. The startup code in an EXE calls
                this function directly, rather than using an _INIT_
                entry, because an address in the user's EXE must be passed.

Return value    none
