This is because this option doesn't exist for SPARC, see the manual.
Why do you think it should work? And what exactly do you mean by
"does not work"?

Subject: Re:  '-mlittle-endian' doesn't work with GCC3.2.3 under 
 Solaris 2.x

Have a look at:

The option -mlittle-endian exists in the manual for SPARC !

http://gcc.gnu.org/onlinedocs/gcc-3.3/gcc/SPARC-Options.html#SPARC%20Options

For GCC 3.2.3 its the same. 

I was wondering anyway since SPARC processors run in big-endian mode.

Ah I see, thanks. The docs are inconsistent: in the overall option
summary, -mlittle-endian is stated for several targets, but not for
sparc, whereas the sparc submodel section has such an entry.

I'll try to figure out who put it in there.

Thanks
  W.

Note that the option is supposed to be supported on SPARC-V9 processors
(Ultrasparc, Ultrasparc3).

OK, I did some archeology -- these options have been listed in invoke.texi
since the very first revision of this file under doc/invoke.texi. Before
that, the file existed in the gcc subdirectory, and there, the option
description dates back to the very first version, checked in by Jeff Law
in August 1997. So I guess these things predate the egcs era.

Eric, you have recently done all the sparc stuff. The compiler just
complains that this option doesn't exist, even if I give
  -mcpu=ultrasparc
so I guess the manual is plain wrong, or what is the answer. I admit that
the manual is at least a) inconsisten (w.r.t. option summary and the sparc
option listing) and b) confusing (w.r.t. which cpu switch has to be given
to allow -mlittle-endian). What do you suggest?

W.

I don't really know for the time being. I'll try to further investigate.

It appears that the -mlittle-endian option is only supported for the triplets:
   sparc64-*-openbsd*
   sparc64-*-elf*
   sparclet-*-aout*

Additionally, -mlittle-endian-data is supported for the triplet:
   sparc86x-*-elf*

Only Linux, OpenBSD and NetBSD seem to be able to handle little-endian code on
SPARC processors.
