workarounds for logb, new modules 'logbf', 'logbl'


From: Bruno Haible
Subject: workarounds for logb, new modules 'logbf', 'logbl'

User-agent: KMail/4.7.4 (Linux/3.1.0-1.2-desktop; KDE/4.7.4; x86_64; ; )

The next math function to be supported by gnulib is logb(), with its
variants logbf(), logbl().

Notable bugs fixed: glibc, Solaris, and Cygwin 1.5.x return a wrong result
when the argument is a denormalized number.
