When the gcc compiler is used on 64-bit Linux that is running on a x86-64 processor, it produces 64-bit code by default. To request it to produce 32-bit code that can be executed on a x86 processor, use the -m32 option:
$ gcc -m32 main.c
For this command to be successful, your Linux installation needs to have the necessary 32-bit libraries needed for gcc to link with.
Tried with: gcc 4.6.3 and Ubuntu 12.04 LTS x64
