When AC_PROG_CC_C99 was added recently we created an implicit
requirement for autoconf version 2.60. This patch makes that
implicit requirement and explicit requirement.

# AC_PROG_CC_C99 is only available in autoconf version 2.60 and later.
# If you must use an older version then comment out the following two
# lines, but be warned that there could be issues with finding the
# nan(), etc. functions. It is really best to upgrade to a supported
# version of autoconf.
