Declare a variable like LIB_CLOCK_GETTIME to be AC_SUBSTituted
right after its initialization, rather than farther down.
Keeping these in close proximity makes it easier to ensure
that each such variable is initialized. E.g.,
LIB_CLOCK_GETTIME=
AC_SUBST([LIB_CLOCK_GETTIME])
This change also increments these serial numbers.
* m4/clock_time.m4 (gl_CLOCK_TIME): Hoist AC_SUBST use.
* m4/euidaccess.m4 (gl_PREREQ_EUIDACCESS): Likewise.
* m4/nanosleep.m4 (gl_FUNC_NANOSLEEP): Likewise.
Setting the envvars, LIB_CLOCK_GETTIME, LIB_EACCESS or LIB_NANOSLEEP
could cause a configure-time and/or build-time malfunction.
Typically, a configure-time function-in-library test is performed
via code like this:
LIB_VAR=
AC_SUBST([LIB_VAR])
prefix_saved_LIBS=$LIBS
AC_SEARCH_LIBS([FUNC], [LIB_NAME],
[test "$ac_cv_search_FUNC" = "none required" ||
LIB_VAR=$ac_cv_search_FUNC])
LIBS=$prefix_saved_LIBS
However, in each of the files affected by this change, the LIB_VAR=
initialization was omitted. Thus, when set in the environment, its
value would propagate into generated Makefiles when FUNC is not found
in LIB_NAME.
* m4/clock_time.m4 (gl_CLOCK_TIME): Initialize AC_SUBST'd var.
* m4/euidaccess.m4 (gl_PREREQ_EUIDACCESS): Likewise.
* m4/nanosleep.m4 (gl_FUNC_NANOSLEEP): Likewise.
99% of this change was performed by running the following commands:
git ls-files | grep '\.m4$' | xargs perl -pi \
-e 's/(AC_\w+\()([^[()]+?)([,)])/$1\[$2]$3/g;' \
-e 's/(AC_\w+\((?:\[[^,]+?\], ){1})([^,[()]+?)([,)])/$1\[$2]$3/g;' \
-e 's/(AC_\w+\((?:\[[^,]+?\], ){2})([^,[()]+?)([,)])/$1\[$2]$3/g;' \
-e 's/(AC_\w+\((?:\[[^,]+?\], ){3})([^,[()]+?)([,)])/$1\[$2]$3/g'
perl -pi -e 's/\[\.\.\.\]/.../' m4/onceonly.m4
The remainder were to add Copyright dates, increment serial numbers,
undo some changes in comments, exclude m4/intl.m4, and add quotes
around the "1" in ",1" where the unusual spacing prohibited the
above regexps from doing the job. For more details, see
