commit 52418c8d828bc25e0e84cc25d5e349a84be0b397
from: Omar Polo <op@omarpolo.com>
date: Fri Feb 12 12:47:20 2021 UTC

fix various compilation errors

Include gmid.h as first header in every file, as it then includes
config.h (that defines _GNU_SOURCE for instance).

Fix also a warning about unsigned vs signed const char pointers in
openssl.
