No, they are not. They enable/disable things, but they are not
preprocessor macros. A USE flage might set or remove certain
preprocessor macros, but that's not necessarily the main purpose
of USE flags.

Read the manual.

Suggestion: Fix your package.keywords and package.mask files. Seems
you've got those files mixed up. Post the line with "app-crypt/gpg-agent-1.9.19"
from package.keywords and package.mask.

How do you see that? A "-" normally means, that something is substracted.
So, I'd be interested to understand how you see that.

It's in the manual. The file /etc/make.conf is your friend here.

Why do you think, that it has debug support?

You know, reading the manual WOULD help. Really. You might be
interested in /etc/portage/package.use

Your questions are answered in the "portage" man page.
