At the moment, building a debug version of Amber requires a bit of ad-hockery in config.h, and doesn't affect some components (those with their own configure scripts that are called by configure) at all.

There were a couple of problems. One is that AMBERBUILDFLAGS wasn't necessarily observed everywhere, tied as it was to CFLAGS, OCFLAGS, FFLAGS and FOPTFLAGS. I've tried to clean that up a bit.
The other is that different compilers have different options. For example, while gcc and gfortran may use the same syntax for enabling warnings and debug symbols, icc and ifort do things a little differently from each other. I can't speak regarding the PGI or Solaris compilers.

I don't have old trees, and couldn't easily find an old configure script in the git repo. Nevertheless, I've put some verbosity options into my own configure script, and shall see what I come up with.

The most recent traffic I could find on the issue was back in January, when Ross redid a bunch of Makefile targets. At that time, it seems he made a decision to include a clean as part of "make uninstall". Would it annoy anyone if I take the "make clean" out of "make uninstall"?
Cheers,
Ben
