# Debug (no optimizations)

# Tiles (uses SDL rather than ncurses)

# Disable gettext, on some platforms the dependencies are hard to wrangle.

# DEBUG is best turned on if you plan to debug in gdb -- please do!
# PROFILE is for use with gprof or a similar program -- don't bother generally
# RELEASE is flags for release builds, we want to error on everything to make sure
# we don't check in code with new warnings, but we also have to disable some classes of warnings
# for now as we get rid of them.  In non-release builds we want to show all the warnings,
# even the ones we're allowing in release builds so they're visible to developers.
