truncl: Simplify for platforms where 'long double' == 'double'. * lib/truncl.c: Include <config.h>. (truncl) [HAVE_SAME_LONG_DOUBLE_AS_DOUBLE]: New function. * lib/trunc.c [!USE_LONG_DOUBLE]: Don't include <config.h> a second time. * m4/truncl.m4 (gl_FUNC_TRUNCL): Require gl_LONG_DOUBLE_VS_DOUBLE. Determine TRUNCL_LIBM according to HAVE_SAME_LONG_DOUBLE_AS_DOUBLE. * modules/truncl (Depends-on): Add trunc. Update conditions.
