* configure.ac (struct tm.tm_gmtoff): Simplify conditional
preproc expression to not use ‘TIME_WITH_SYS_TIME’, and instead
#include <time.h> unconditionally.
* libguile/filesys.c: Simplify conditional preproc expression
to not use ‘TIME_WITH_SYS_TIME’, and instead #include <time.h>
unconditionally.
* libguile/posix.c: Likewise.
* libguile/gen-scmconfig.c: Likewise, for generation code.
* configure.ac (guile_cv_need_braces_on_pthread_once_init)
(guile_cv_need_braces_on_pthread_mutex_initializer): Add
‘AC_LANG_PROGRAM’ call to first arg of ‘AC_COMPILE_IFELSE’.
These days, Emacs' Autoconf mode has proper support for
‘dnl’ in ‘comment-start’, ‘comment-end’, ‘comment-start-skip’;
we no longer need to specify these explicitly.
* configure.ac: Remove EOF "Local Variables" block.
