[Zhu ZhenXiong]

Hi,
    I'm a new user, so I don't 
known how to use the gcc exactly.
    Would you like to help me and 
tell me about how to build the 32bit standed alone
exe file?
    I only known use it like this: 
gcc -o myfile.exe myfile.c
the output file myfile.exe is a 16bit DOS 
program?
 
Hope get your help.
Thanks.
