The gcc way is to use an "asm block", like so:

void SetMCGA()
{
   asm ( "mov $0x13,%%ax;"
         "int $0x10;"::: "ax" );
}

However you've got a bigger problem. Attempting this code in a windows app 
will just cause
a violation and kill your program.

You can do this if you're writing to DOS (I imagine it's fine in djgpp), 
but not windows.

If you want access to the display in windows use SDL or DirectX (or OpenGl, 
Allegro etc, etc, etc...)
