commit 9d7e3be1c86ad2629f6146b6957675b6fbccd2fa
Author: Gregory W. Chicares <gchicares@sbcglobal.net>
Commit: Gregory W. Chicares <gchicares@sbcglobal.net>
Import header from fdlibm
This is a pristine copy of netlib.org source:
wget -O fdlibm.h
"http://www.netlib.org/cgi-bin/netlibfiles.txt?format=txt&filename=fdlibm%2Ffdlibm.h"
The '.txt' suffix lets it elude lmi's concinnity checks for now.
