If i compile test-gui.c with this commandline:
tcc.exe test-gui.c -nostdlib -Wl,--subsystem,gui
test-gui.exe is still commandline program PE_EXE and
it does not follow pe.subsystem value that should be 2 PE_GUI
and should use _winstart startpoint.
--- test-gui.c ---
int _winstart(void)
{
return 0;
}
--------------------------------------------------------
With this patch it's possible to use _winstart without runtime libraries:
tcc.exe test-gui.c -nostdlib
