That's odd, since I just tried it and it worked for me. That is, I ran

./gnulib-tool --create-testdir --dir foo -h year2038-recommended

and saw this output from configure when run on gcc45.fsffrance.org:

...
checking for gcc -std=gnu11 option to enable large file support... 
-D_FILE_OFFSET_BITS=64
checking for gcc -std=gnu11 option for timestamps after 2038... support 
not detected
configure: error: in `/home/eggert/foo':
configure: error: could not enable timestamps after mid-January 2038.
Did you mean to build a 64-bit binary? (E.g.,
'CC="gcc -std=gnu11 -m64"'.) To proceed with 32-bit time_t,
configure with '--disable-year2038'.
See `config.log' for more details

with exit status 1, and I ran

./gnulib-tool --create-testdir --dir bar -h year2038

and saw this output from configure:

...
checking for gcc -std=gnu11 option to enable large file support... 
-D_FILE_OFFSET_BITS=64
checking for gcc -std=gnu11 option for timestamps after 2038... support 
not detected
...

with an otherwise-successful run.
