--- Comment #1 from duser at neet.fi ---
looked at this some more, the syntax error seems related to using a D type for
the cast - size_t is implicitly imported from object.d in the example so it's
not really a valid C program

the error in v2.099.0 was already fixed by
https://github.com/dlang/dmd/pull/13736 but the cast with D types became a
syntax error with https://github.com/dlang/dmd/pull/13831

here's a better example than the first one:

// test.c(2): Error: found `1` when expecting `]`
// test.c(2): Error: `=`, `;` or `,` expected to end declaration instead of `]`
__import core.stdc.stdint;
char cs[(int32_t)1];
