| On the c compiler provided with the RISC os for their mips

| in little endian.
| 
| gcc does not apear to have such an option of its command line.
| There are #defines that you can use,  it seems, to say which 
| type of endianness you want, when you build gcc.
| 
| I realy don't want to have two gcc executables (one for big and
| one for little endian.)  I'd like a command line argument
| to be able to switch between the two.  Is that going to exist
| in a future gcc release, or is it posible to hack on the code
| to produce big/little endian as definable by the user?

GCC internally is not set up to be able to switch endianess at
runtime.  If you look in the sources, you will see a number of places
that use #ifdef's in the middle of expressions that control the
endianess.  Obviously, it could be done, but so far it hasn't been.

While you would still have to have two executables, you could switch
endianess via the -b <machine> switch and only have one driver program.
