eCos uSTL port patch for review

[cetoni GmbH - Uwe Kindler]

Hi John,

to get this right - you would like to keep the original uSTL #if ... 
definitions in the uSTL source instead of my #if defined ... changes and 
  to define the macros to 0 in config.h so that the changes to uSTL 
source are kept to a minimum and most of the changes are in eCos 
specific config.h file? But you would prefer to see my #if defined ... 
changes in the official uSTL tree of Mike Sharov?

O.k., i will provide a patch.

I already tried this but it is hard to track all dependencies. Therefore 
I would propose the following strategy:

Step 1:
If I implemented all of your change requests the uSTL library goes into 
the eCos CVS

Step 2:
If the uSTL library is in the eCos CVS it can be optimized by me or by 
other users by making the package more configurable.

A last question. The uSTL eCos package contains a stdint.h file because 
eCos libc does not provide one. Would you prefer to see this file in the 
libc library or should it stay in uSTL package.

Regards, Uwe
