gl_STRING_MODULE_INDICATOR - look at how it's defined in m4/string_h.m4 - only
sets some variable and arranges for some #define in config.h. It never prints

gl_FUNC_STRERROR - look at m4/strerror.m4 - prints nothing if previous tests
have already determined that errno.h must define additional errno values.

strftime: See 
The gnulib module 'strftime' does not define a function named strftime(), but

strptime: See 
and m4/strptime.m4. It does an AC_CHECK_FUNCS_ONCE([strptime])
but you did not see it there because all AC_CHECK_FUNCS_ONCE invocations are
handled near the beginning of the 'configure' run.

getdate: never supplied by the system.

strerror: See above.
