9088826695 Removed confusing text which implies that gamma() computes the gamma 
instead of log gamma function.  This was true with 4.4BSD's libm, but
they are equivalent on all other systems (XPG4.2 requires this).

af726e9c88 PR/3405: Krister Walfridsson: Various typos; since we compile with POSIX 
libm, we should not xref matherr(3), and describe the errno settings.

c1c8f42080 Changed core routines to call __ieee754_sqrt() instead of sqrt(). I 
reported this enhancement to fdlibm-comments, and got the following

You are right. __ieee754_sqrt should be in use with e_*.c.
