Oh, interesting - that didn't even occur to me.
Out of curiosity I just tried the same in msvc... the intellisense in
Visual Studio highlights it as an error, but it builds and runs fine.

Hey All,
First post here. Firstly, thank you all for your work on this
project. I discovered tcc just a month or so ago and really enjoying
using it as a back-end code generator for a custom scripting language
I'm working on.
Anyway, I noticed this small bug:
A variable declaration as the first statement in a switch case block
fails when it shouldn't:
case 1:
int z = 123; // This fails with "identifier expected"
break;
Hi,
well, yes, no. As a fact, a variable declaration is not a
statement.
There's a pretty easy workaround, just insert an empty statement
before.
case 1:
; // This fixes it
int z = 123;
break;
Yes, label before statement is allowed, also label before empty
statement, just not label before no statement.
As for example "label: }" is not allowed either (in the theory).
See also what gcc has to say:
test.c: In function 'main':
test.c:7:23: error: a label can only be part of a statement and a
declaration is not a statement
switch(a) case 1: int z;
^~~
Which of course if a lot better than just "identifier expected"
I would agree that far.

(this was build of the mob repo on github - not sure if that affects
things).
