Re: How to remove extra assembly code

I used IDA pro to reverse engineer test.exe and found that gcc added "call __main" to the 
front of the assembly code, and then executed "jmp __do_global_ctors". I guess this code 
means to instantiate C++ objects.

Yes, mostly.

My code is pure C language and does not need this code. How to remove the extra 
assembly code.

Note the call still exists, before your main function is called.

The solution is to define `WinMain()` (or `wWinMain()` with the `-municode` option), where GCC will not insert `__main()`.
