The Makefile editor does not recognize macro
definitions for syntax coloring, that is, if you
had the definition PATH=/usr/bin, the macro PATH
should be recognized and its color should be
settable. Also, the color for Makefile Targets is
overridden by the color for Makefile identifier.
Downgraded to P3.
This is a desirable enhnacement for a follow-up release
Makefile color scheme is now configurable in Tools->Options->Fonts & Colors.
Macro definitions are still not highlighted, but macro usages are.
