# every time the modules that use them are recompiled, whether they are

define GHSWARNING1

WARNING: proj/globalhs is not tagged consistently. A build of any target 
in proj/globalhs will fail. The output of script 
proj/globalhs/scripts/checkglobalhstags is "$(GLOBALHS_TAG)".

To skip tag checking (FOR DEVELOPMENT ONLY!), specify GLOBALHSTAGOVERRIDE 
in either your environment or on the make command line. The value of 
GLOBALHSTAGOVERRIDE must contain the string "globalhs". This value will 
be compiled into the modules and written to ancillary dataseries as CVSTAG.

To automatically create a consistent tag (FOR PRODUCTION ONLY!), one may run 
proj/globalhs/scripts/setglobalhstags. This script will add a tag in cvs 
for every file comprising the globalhs source code, so use it with care.

The value given was "$(GLOBALHSTAGOVERRIDE)".
