Bruno Haible fddec5c1 2011-09-30T21:07:43 float, math: Fix 'int' to 'long double' conversion on Linux/SPARC64. * m4/float_h.m4 (gl_FLOAT_H): Test conversion from 'int' to 'long double'. Set REPLACE_ITOLD. * lib/float.in.h (_Qp_itoq, _gl_float_fix_itold): New declarations. * lib/math.in.h (_Qp_itoq, _gl_math_fix_itold): New declarations. * lib/itold.c: New file. * modules/float (Files): Add lib/itold.c. (configure.ac): When REPLACE_ITOLD is 1, arrange to compile itold.c. (Makefile.am): Substitute REPLACE_ITOLD. * modules/math (Depends-on): Add float. (Makefile.am): Substitute REPLACE_ITOLD. * doc/posix-headers/float.texi: Mention problem on Linux/SPARC64. * doc/posix-headers/math.texi: Likewise. * doc/posix-functions/logl.texi: Likewise.
Bruno Haible b14c9a8f 2010-10-02T18:35:08 Update doc for POSIX:2008. * doc/posix-headers/*.texi [except ucontext.texi, sys_timeb.texi]: Update URL of POSIX specification.
Karl Berry 80fc442c 2010-08-13T11:50:58 avoid some overlong lines from posix urls, etc.
Eric Blake 833333f7 2008-04-12T07:22:40 Work around Solaris 10 math.h bug. * m4/math_h.m4 (gl_MATH_H): Check for bug. (gl_MATH_H_DEFAULTS): Set up default. * modules/math (Makefile.am): Replace new indicators. * lib/math.in.h (NAN, HUGE_VAL): Provide replacements. * tests/test-math.c (main): Test this. * m4/strtod.m4 (gl_FUNC_STRTOD): Don't rely on HUGE_VAL. * doc/posix-headers/math.texi (math.h): Mention bug.
