"make config" still runs to completion.

checking for update-desktop-database... /usr/bin/update-desktop-database
./configure: line 4254: GUILE_FLAGS: command not found
checking Guile version >= 1.6.0... info: No menu item `guileversion' in node `(dir)Top'.

./configure: line 4270: test: : integer expression expected
./configure: line 4271: test: : integer expression expected
checking whether scm_is_string is declared... no

Hmmm... I wonder if we need to use the 0"$x" syntax to force them all
to be integers?  Or just check to see if they're set at all before
trying to use them?
