Tom has (graciously) allowed me access to his Irix 5.3 system to attempt
to address this.  On that platform, 'long double' and 'double' are
identical types.  The test ends up calling sprintf(tmp, "%Ld", -0.0L), but
the system sprintf does not know how to print -0, so the result is
0.000000 and lacks -.  Does it make more sense to adjust the existing
gl_PRINTF_INFINITE_LONG_DOUBLE (which also tests for NaN) to add a test
for negative zero, or to add a new macro gl_PRINTF_ZERO_LONG_DOUBLE?  I
can probably do most of the work, since I can test it on the Irix box, but
would like to make sure that I'm meeting your preferred style.
