[PATCH] gengtype: do not skip char after escape sequnce

[Martin Liška]

Right now, when a \$x escape sequence occures, the
next character after $x is skipped, which is bogus.

The code has very low coverage right now.

Patch can bootstrap on x86_64-linux-gnu and survives regression tests.

Ready to be installed?
Thanks,
Martin

gcc/ChangeLog:

        * gengtype-state.cc (read_a_state_token): Do not skip extra
        character after escaped sequence.
