A practical example of this problem can be seen in the inability to build
XFree86 v3.3.2.3 for i386 RedHat Linux with v1.1a of the pgcc/egcs compilers. 
Because __i386__ is not defined, the symbol LinuxMachineDefines is not resolved,
causing the compile of each source file to fail.

That's Not Good.

It has been pointed out to me that this isn't really true. An earlier
version of egcs (1.0.3 IIRC), had fixed this, but the __i386__ has been
removed again in 1.1.

In packaging 1.1 for Debian, I noticed a similar problem for alpha:
gcc/config/alpha/linux.h doesn't put -D__alpha in CPP_PREDEFINES .

While there may be valid reasons for cleaning out CPP_PREDEFINES, I think
this issue should be addressed in the egcs FAQ, and a suggestion for a
workaround for imake be included.
