+ m4: stylistic-only: hoist AC_SUBST to be adjacent to initialization
+ 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])

+
+ don't let environment settings perturb build
+ 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.
