HI,
Here is a possible that you are useing one of 386 memory manager for inst.
QEMM, EMM386, or protect mode control program for inst. TDH386.SYS, TKERNEL,
DPMIRES, etc.
Every of these programs make a Virtual 86 enviroment and not allow your
GCC to switch in protect mode.
QEMM make VCPI DOS extender that can be use by gcc. But DPMI {Windows, OS2}
DOS extender or many others can not be used by your gcc to allow gcc to switch
in protect mode 386.
Try to uninstall some memory manager from your CONFIG.SYS or AUTOEXEC.BAT or
don't run gcc from MS Windows or OS/2 enviroment.
