Endian[n]ess, language-specific problems and help with egcs.

[Smith]

I was wondering if there is a list of what endian[n]ess 
a CPU/OS uses. I also realize that it's more complicated
in that some CPU's like PPC support LE in addition to BE, 
so does that mean that PPC's are BE under MacOS/Linux/BeOS,
and LE under NT?

And from what I've read, it also appears that Alpha and 
SGI have some kind of support for both BE and LE.

I've also seen somewhere that VAX seemed to use neither BE 
('1234') or LE ('4321'), but instead '2143' or something 
like that. Is that right?

I ask this to the egcs list since I'm assuming that the 
compiler writers would know this topic in excruciating 
detail. ;)
