* sysdeps/i386/fpu/s_nextafterl.c: Add __nextafterl and nextafterl
aliases.
* sysdeps/ieee754/flt-32/e_lgammaf_r.c: Don't handle -Inf special.
* sysdeps/ieee754/flt-32/e_gammaf_r.c (__ieee754_gammaf_r): Check
for -Inf and return NaN.
* math/gen-libm-test.pl: Fix program name in help message.
* math/libm-test.inc (check_complex): It's Imaginary, not Complex.
* math/libm-test.inc (gamma_test): Result of gamma(-inf) is +inf.
* sysdeps/i386/Implies: Correct order of libm directories.
