One other thing-- it is advisable to create parser.c any time parser.l
changes. I noticed that one reason a recent build (directly from git)
failed was because parser.c was not up to date, and so flex was
required. This situation is only going to cause trouble for people
trying to build xboard themselves. Best to make sure the parser.c in
the winboard directory is always up to date (in particular, wrt
timestamp) so that make will not try to generate it from parser.l.
Xboard/parser.c is in not in git and always needs to be generated. Not
sure about the parser.c in the winboard directory, perhaps HGM can tell
us if winboard can use the same as xboard... I'll put it on my list of
things to check before a release though. Thanks for pointing it out.
