--enable-{debug,cassert} should also activate --enable-depend

[Dimitrios Apostolou]

Hello list,

I just spent 2 miserable days tracking down a very weird issue. I ended up 
stepping through the code in the debugger. As it turned out, the very same 
moment of execution, one datastructure (struct _restoreOptions defined in 
pg_backup.h) contained different fields on one data frame than another! 
This was the result of one object file *not* being re-compiled as needed, 
after applying my patch that added that extra field to the datastructure 
in pg_backup.h.

This caused weird and completely irrelevant failures, as unexpected fields 
of the struct were changing value.

I then found that I need to compile with --enable-depend to have Makefiles 
with proper dependency tracking. Shouldn't it be the default, at least for 
non-release builds?


Thanks,
Dimitris
