Lovely!

Thank you!

I found a C99 parse bug after we refactored Mes' src/display.c:
declacing a variable as first statement of a `case' statement gives

--8<---------------cut here---------------start------------->8---
$ MES=guile ./pre-inst-env mescc switch.c 
switch.c:8: parse failed at state 623, on input "int"
--8<---------------cut here---------------end--------------->8---

See attached file.  As Mes currently supports NYACC >= 1.00.2 (we should
probably raise that requirement, for the new bootstrap we use latest
greatest anyway to be able compile latest tcc), I've moved the
statements inside case into a block; so there's no urgency at all from
our side.

Greetings,
Janneke
