[Greg Chicares]

branch: master
commit 0401064d7b120447d22a58068dc9a54fcc21eeec
Author: Gregory W. Chicares <address@hidden>
Commit: Gregory W. Chicares <address@hidden>

    Set multiple variables
    
    Test thus, e.g.:
      $export LMI_IN=G; LANG=fr_CA make -f parent.make all
    It is important to make sure that multiple variables are set correctly.
