In this example I get a spurious error, but only when I elide some

};
$ ./tcc a.c
a.c:6: error: cast expected
Some compilers accept it but issues warning (with -Wall).
The following should always be valid:
struct {
struct {
int i;
} a;
} x = {
{3}
};
At least according to C99 not all parenthesis are necessary if there is
no ambiguity. It's a known bug but nobody found time / interest to work
on this yet. Maybe for tcc 0.9.27 as I remember grischka warning that
the current code is not adapted to detect this and some important
changes would be needed.
Best regards,
