# 1.7 12-Sep-2016 guenther

Reduce libm's exports and make internal calls go direct.
All dependencies on libc are now via reserved/standardized names.

It's been a quarter century: we can assume volatile is present with that name.

# 1.3 29-Apr-2011 martynas

Trick GCC (-O2) into actually raising the underflow exception on m88k.

Since the second division operand is a power of two, non-zero,
non-nan, this got optimized (-O2) into multiplication. As a result
the underflow exception wasn't being raised properly.

Make the second operand a volatile to prevent incorrect optimizations.

OK miod@.
