* m4: rewrite __attribute__((unused)) checkDmitry V. Levin2020-08-071-32/+0
| | | | | | | | | Rewrite using AC_CACHE_CHECK to create a more readable autoconf macro. * m4/attribute.m4: New file. * m4/japhar_grep_cflags.m4: Remove. * m4/.gitignore: Replace japhar_grep_cflags.m4 with attribute.m4. * configure.ac: Replace AC_C___ATTRIBUTE__ with PAM_ATTRIBUTE_UNUSED.
* configure.ac: rewrite WARN_CFLAGS initializationDmitry V. Levin2020-08-061-16/+0
| | | | | | | | | | | | | As the old machinery was not prepared for adding compiler options conditionally when the compiler supports them, replace it with a new machinery that implements this. * m4/warnings.m4: New file. * m4/warn_lang_flags.m4: Likewise. * m4/.gitignore: Add exclusions for them. * m4/japhar_grep_cflags.m4 (JAPHAR_GREP_CFLAGS): Remove. * configure.ac: Call pam_WARN_LANG_FLAGS. Remove all uses of JAPHAR_GREP_CFLAGS.
