Try: Findstr /s /n /r /c:"[^a-z]main[^a-z]" *.c You will see the related codes for linking stage, together with the crt codes. You known what linking does, you get the points. I think it needs _start/_wstart pairs and linking process. I searched gcc and ld codes to see how it could be made, but didn't get it. > > > On Sat, Jul 5, 2014 at 4:52 PM, YX Hao <[email protected]> wrote: > > > Something more, on windows use a Unicode console environment is not > convenient.

Some one experienced, like grischka, may be interested to implement this capability for TCC.
