* data/glr.c, data/lalr1.cc, data/yacc.c: Do not use __file__,

since this causes problems when __file__ contains character
sequences like "@" that are treated specially by src/scan-skel.l.
Instead, just use the file's basename.  This fixes the bug
reported by Martin Mokrejs in
<http://mail.gnu.org/pipermail/bug-bison/2002-December/001949.html>.
