And the IEEE tests for these functions fail on Solaris and NetBSD 5.1:
  log(negative) = -Inf (should be NaN)

Workarounds added:

        logf-ieee: Work around test failure on NetBSD 5.1.
        * m4/logf-ieee.m4: New file.
        * m4/logf.m4 (gl_FUNC_LOGF): If gl_FUNC_LOGF_IEEE is present, test
        whether logf works with a negative argument. Replace it if not.
        * lib/logf.c (logf): For negative arguments, return NaN.
        * modules/logf-ieee (Files): Add m4/logf-ieee.m4.
        (configure.ac): Invoke gl_FUNC_LOGF_IEEE.
        * doc/posix-functions/logf.texi: Mention the logf-ieee module.

        logf-ieee: Work around test failure on Solaris 9.
        * modules/logf-ieee (Depends-on): Add log-ieee.
        (configure.ac): Require gl_FUNC_LOGF.

        log-ieee: Work around test failure on NetBSD 5.1 and Solaris 11.
        * m4/log-ieee.m4: New file.
        * m4/log.m4 (gl_FUNC_LOG): If gl_FUNC_LOG_IEEE is present, test whether
        log works with a negative argument. Replace it if not.
        * lib/log.c (log): For negative arguments, return NaN.
        * modules/log-ieee (Files): Add m4/log-ieee.m4.
