malcolm: Tue Aug 6 15:47:24 CEST 2002 Update of /usr/src/master/nhc/src/hmake In directory hinken:/tmp/cvs-serv382 Modified Files: Argv.hs GetDep.hs Makefile MkConfig.hs Added Files: RunAndReadStdout.hs PackageConfig.hs Log Message: Better handling of package libraries. Previously, the package import directories were detected at installation time, so the addition of a new package required a re-configure of hmake. Also, because all of the package dirs were searched on every invocation, hmake could not warn of a missing `package' flag. Now, package dirs are detected at runtime, and only for the requested packages - this fixes both problems.
