Hmm, let's see ... I'm fairly sure to have the .def file problem fixed

Both in mob now. I've tested 32bit and 64bit linux; some proper Windows
testing would be nice. (I've also checked in your improved variant of
the asm-c-connect test)
I like it. More lines removed than added could mean that it is
going in the right direction anyway ;)

Question: I wonder whether now we could maybe get rid of the asm label
"post-processing" (asm_free_labels) and the asm_label stack altogether?
Seen that it can be counter-productive too, as with for example:
t1.c:
int main_2();
int main() {
asm("call x5");
return main_2();
}
int x5() {
printf("x5\n");
return 5;
}
t2.c:
int main_2() {
x5();
return 0;
}
$ tcc -c t1.c t2.c && tcc t1.o t2.o -o t.exe && t.exe
tcc: error: undefined symbol 'x5'
$ tcc -c t1.c && objdump -x t1.o
SYMBOL TABLE:
00000000 l df *ABS* 00000000 t1.c
0000004a l .text 0000001f x5
Here 'x5' should have the g[lobal] binding from C.
