Simply to distinguish the official releases of toolchains (I hope well
tested) and any home-cooked toolchains. I meant such predefined things
for GCC (CPP)

  % i386-rtems4.11-gcc -dM -E - </dev/null | grep __rtems__
  #define __rtems__ 1

and the same we could have for officially supported releases for ecos,
e.g.

  % i386-ecos3.12-gcc -dM -E -</dev/null | grep __ecos__
  #define __ecos__ 1

Secondly, it lets anyone to use such checks in sources, e.g.

  #if __linux__
  # include <endian.h>
  #elif __ecos__
  # include <machine/endian.h>
  #else
  ...
  #endif

For now we usually add '-D__ECOS__' to CFLAGS for some packages.

The third, Why we should avoid to say that eCos is also well known,
widely used OS?

Nope. Anyone can use own binaries if he/she wants.

Why it will be not possible? I did not understand. You can use own, but,
a bug reporter should/may use officially supported "labeled" toolchain
to check the roots of some issue on crashes. But, naturally, I do not
resists on built-in label __ecos__. Look on that as a promotion eCos OS.
If you think that my points are wrong, please, forget it.

Thanks for your comments.
