Given that tcc_add_library() takes a TCCState it seems to me
that a call shouldn't persist to subsequent TCCStates.
This example seems to show that it does.
$ tcc -version
tcc version 0.9.28rc 2024-06-11 mob@08a4c52d (AArch64 Linux)
$ tcc tcc-add-library-bug.c -ltcc && ./a.out
tcc_add_library=0
tcc: error: undefined symbol 'atan'
tcc_add_library=1
3.14159
tcc_add_library=0
3.14159
Thanks - Eric
