Yup, I’m building 2.2.3.  I see mktime.c in guile-2.2.3/lib, but do not see
mktime.o when I objdump libgnu.a, indicating that it’s not being built.

In config.log, I see a few lines that could be relevant:

configure:34662: checking for working mktime
...
gl_cv_func_working_mktime=yes
...
GNULIB_MKTIME=‘1'
...
REPLACE_MKTIME=‘0'
...
gl_GNULIB_ENABLED_mktime_FALSE='#'
gl_GNULIB_ENABLED_mktime_TRUE=‘'

(full config.log is here: https://gist.github.com/mkeeter/81c273069a2804ad8d53e72533f6f8da)

Does this offer any insight?  I’m confused by the conflicting GNULIB_MKTIME vs
gl_GNULIB_ENABLED_mktime_TRUE, but am not adept at parsing automake outputs…
