Found this while cross-compiling:

checking where to find the exponent in a 'double'... checking whether byte
ordering is bigendian... no
word 1 bit 20
checking whether isnan(float) can be used without linking with libm... yes
checking whether isnan(float) works... guessing yes
../configure: line 14918: test: too many arguments

This patch does not address the first bug (namely, that the check for
exponent inside double and bigendian are nested, which is a no-no for
output purposes); but does address the second.

        * m4/isnanf.m4 (gl_FUNC_ISNANF_NO_LIBM): Avoid syntax error on
        cross compiles.

Don't work too hard, make some time for fun as well!
