Fix minor problems encountered by a fresh bootstrap.

Fix minor problems encountered by a fresh bootstrap.

* data/glr.c, data/yacc.c: Do not use apostrophes in '#' comments,
as they confuse xgettext, which tries to parse them as C character
constants in a preprocessor directive.
* data/yacc.c (yy_lac): Don't use printf %d format on *yyesp, as
that expression might not promote to int on some platforms.
* src/parse-gram.c, src/parse-gram.h: Regenerate.
