b09c293f1a Clean the usage of spot::acc_cond::mark_t
spot::acc_cond::mark_t is implemented as a bit vector using a single
unsigned, and implicit conversions between mark_t and unsigned may be
confusing. We try to use the proper interface.

ac6b0c9432 include config.h in all *.cc files
This helps working around missing C functions like strcasecmp that do
not exist everywhere (e.g. on Cygwin), and for which lib/ supplies a
replacement.  Unfortunately we do not have such build in our current
continuous integration suite, so we cannot easily detect files where
such config.h inclusion would be useful.  Therefore this patch simply
makes it mandatory to include config.h in *.cc files.  Including this
in public *.hh file is currently forbidden.

81e5357e62 fix handling of Rabin-like input for dnf_to_dca()
The bug is mentioned by Maximilien Colange in a comment to issue #317,
