You'd need to borrow some code from tccrun.c plus write some additional
code so "rt_printline" can access the .stabs sections in the exe/dll
and then you'd put all that into a library that tcc would link into your
exe/dll if say -g is given.

Not trivial but possible, as running through gdb shows:

$ tcc -g test.c
$ gdb test.exe
