From: Arjan Knepper (arjan.knepper_at_[hidden])
Date: 2006-04-14 09:16:56

Attached patch for v2/tools/dmc.jam

The v2/example/hello and v2/example/libraries should build & run with 
this patch.

Issue to fix:
-WD cflag should be added only whem compiling sources for a shared lib (dll)
-WA cflag should be added when compiling sources for executables (exe) 
and static libs (lib)
