FDLIBM -- Sun Microsystems, Inc.

The notice below is reproduced verbatim.  It is the whole of the licence:
its single condition is that the notice itself be preserved, and this file
is that preservation.

It appears in this form at the head of every FDLIBM float file in the GNU C
Library that ArWen transcribes -- sysdeps/ieee754/flt-32/s_expm1f.c,
s_tanhf.c, s_atanf.c, e_log10f.c and e_lgammaf_r.c -- and in glibc's own
LICENSES file under the heading "Files from Sun fdlibm are copyright Sun
Microsystems, Inc.".

The same notice, as glibc's LICENSES file presents it without the C comment
decoration:

    Files from Sun fdlibm are copyright Sun Microsystems, Inc.:

Netlib's original double-precision FDLIBM 5.3 carries the same notice with
"SunSoft" in place of "SunPro"; the float files, which are the ones ArWen
transcribes, say SunPro.  The float conversions themselves were made at
Cygnus Support by Ian Lance Taylor -- netlib FDLIBM 5.3 ships no float files
at all ("only double precision is supported") -- and glibc carried the line
"Conversion to float by Ian Lance Taylor, Cygnus Support" until it stripped
those headers in commit 30891f35. Cygnus attached no separate condition;
Sun's notice above is the one with conditions, and it is the one preserved.
