# FP_COMPUTE_INT(EXPRESSION, VARIABLE, INCLUDES, IF-FAILS)

# compilation. Execute IF-FAILS when unable to determine the value. Works for
# cross-compilation, too.

# is supported in autoconf versions 2.50 up to the actual 2.57, so there is
# little risk.
# The public AC_COMPUTE_INT macro isn't supported by some versions of
# autoconf.
