strerror: drop strerror_r dependency Since the errno module is responsible for introducing replacement errno values, it should also be responsible for translating those new values into strings. And by moving the replacements into a file managed by the errno, we can then break the dependency between strerror and strerror_r, so that strerror no longer drags in multi-threading modules required by strerror_r. Tested on glibc with: gl_cv_header_errno_h_complete=no gl_cv_func_working_strerror=no \ gl_cv_func_strerror_r_works=no ./gnulib-tool --with-tests \ --test strerror strerror_r-posix * lib/strerror_r.c (strerror_r): Move gnulib replacement strings... * lib/strerror-override.c (strerror_override): ...to new file. * lib/strerror-override.h: Add prototype. * lib/strerror-impl.h: Delete. * lib/strerror.c (strerror): New implementation. * modules/errno (Files): Add new files. (configure.ac): Compile new file as appropriate. * modules/strerror (Files): Drop unused file. (Depends-on): Drop strerror_r-posix. * MODULES.html.sh: Document strerror_r-posix.
