* lib/cosl.c (cosl) [HAVE_SAME_LONG_DOUBLE_AS_DOUBLE]: New alternative implementation. * m4/cosl.m4 (gl_FUNC_COSL): Require gl_LONG_DOUBLE_VS_DOUBLE. Determine COSL_LIBM according to HAVE_SAME_LONG_DOUBLE_AS_DOUBLE. * modules/cosl (Depends-on): Add cos. Update conditions. (configure.ac): Don't compile sincosl.c and trigl.c if HAVE_SAME_LONG_DOUBLE_AS_DOUBLE.
