| | | | | | * lib/strerror_r.c: Include <stdarg.h>. (strerror_r): Provide error messages for errno values 100...140. * doc/posix-functions/strerror_r.texi: Mention the MSVC 14 problem.
* Target a C99 subset, not a C89 subsetPaul Eggert2017-04-234-32/+125
| | | | | | | | | | | | | | | | | | | | For many years Gnulib has targeted C89 and has resisted using C99 features, as some Gnulib-using programs still wanted to target C89. As this no longer seems to be the case, relax the porting requirements to allow some C99 features. This is merely a change to the documentation, to give other Gnulib developers a chance to weigh in on the topic. * doc/extern-inline.texi (extern inline): * doc/gnulib-readme.texi (Portability guidelines): * doc/gnulib-tool.texi (Initial import): * doc/gnulib.texi (Header files): Modernize to talk about C99 and C11 instead of C89 and C99. * doc/gnulib-readme.texi (Portability guidelines): Now a section, not merely a subsection, so that it can be split up. Modernize a bit. (C language versions, C99 features assumed) (C99 features avoided): New sections.
* doc: New section "Modules that modify the way other modules work".Bruno Haible2017-04-231-0/+72
| | | | | * doc/gnulib.texi (Modules that modify the way other modules work): New section.
* getlogin_r: Work around bug in Mac OS X 10.12.Bruno Haible2017-04-231-1/+1
| | | | | | | | | * m4/getlogin_r.m4 (gl_FUNC_GETLOGIN_R): Test also against the Mac OS X bug. * lib/getlogin_r.c (getlogin_r): When getlogin_r returns a string of the given size minus 1, call getlogin_r a second time, on a larger buffer. * modules/getlogin_r (Depends-on): Add malloca. * doc/posix-functions/getlogin_r.texi: Mention the Mac OS X bug.
* *printf: Work around rounding bug on Mac OS X.Bruno Haible2017-04-2212-0/+48
| | | | | | | * m4/printf.m4 (gl_PRINTF_DIRECTIVE_A): Test for Mac OS X 10.12 bug. * doc/posix-functions/*printf.texi: Mention the rounding bugs of Mac OS X and FreeBSD. * doc/glibc-functions/*printf.texi: Likewise.

* gnulib-tool: new option --gnu-makePaul Eggert2017-03-122-17/+19
| | | | | | | | | | | | This is for applications like GNU Emacs that use GNU Make features instead of Automake. * doc/gnulib-tool.texi (Initial import): Mention --gnu-make. * doc/gnulib.texi (Unit test modules, Build robot for gnulib): Do not assume Automake. * gnulib-tool (func_determine_path_separator) (func_modules_transitive_closure, func_update_file) (func_emit_lib_Makefile_am, func_emit_tests_Makefile_am) (func_import): Add support for --gnu-make.
