gpsee_config.mk dependency generated incorrectly in depend.mk

[GoogleCodeExporter]

I've run into this sort of problem several times. gpsee_config.h is thought to 
be in some other directory by depend.mk sometimes and upon make install can't 
be found there. "rm depend.mk ; make depend.mk" remedies that problem, but i'd 
like to figure out why i keep running into it and how to fix it.

Does this also happen with non-SureLynx builds?

I know (approximately) what this is, though.

What happens is that when you build GPSEE, makedepend runs.  (makedepend is gcc 
-M in GPSEE build, but it basically works the same as the traditional 
makedepend).

Okay, so makedepend runs, and automatically generates your dependencies.  
Rather than dump them at the end of the makefile as is tradition (ugh), I put 
them in depend.mk.

Then, some how, your /var/surelynx/include/apr_surelynx directory vanishes but 
your depend.mk file did not get blown away.

*clue* - were you building on my zone?  I blew away my includes on Friday as a 
debug step while working on ./configure.

There's an interesting point in this discovery, though, it means that the 
dependency generator thinks $(INCLUDES)/gpsee_config.h has a higher precedence 
than $(GPSEE_SRC)/gpsee_config.h.  That's probably a subtle problem we should 
look at.

I'm not sure I can answer anything about this bug with any confidence, but I am 
going to keep my eyes open and try not to let this go forgotten.
