Some grepping and reading suggest this message comes from m3front/src/misc/Host.m3:158,
procedure ProcessArg.  This would accept "-NoChecks", note the dash.

Some more poking around reveals it gets these options from Quake variables
M3_OPTIONS and M3_FRONT_FLAGS.

Despite the name "ProcessArgs" and the use of dashes on everything, these
don't appear to be command line options, which are handled in entirely
different paths.  Command line "-A" looks to get converted to "-NoAsserts"
and appended to M3_OPTIONS by generated Quake code, to be interpreted later.
There are a few other such conversions, but nothing else starting with "-No..."
