[Stgt-devel] [PATCH] Makefile auto dependencies

[Alexander Nezhinsky]

Tomo,

Sorry. The patch isellf was ok, but gmail wrapped the line
with TGTD_OBJS as it was longer than 80 chars.
Remailing it from other mailer.

---
Added automatic dependencies generation to stgt Makefile.
Dependency files are generated using -MM flag of gcc and included to
the Makefile itself.
Also .PHONY target declarations added where appropriate.
