%description
RTEMS is an open source operating system for embedded systems.

This is gcc's and newlib C Library's sources with patches for RTEMS.

 The original sources are not included in the source RPM.
 If we included them, then the source RPMs for each target
 would duplicate MBs of source unnecessarily.  This is 
 a duplication of over 30 MBs of source for each of
 the more than 10 targets it is possible to build.

 You can get them yourself from the Internet and copy them to
 your /usr/src/[redhat|packages]/SOURCES directory ($RPM_SOURCE_DIR).
 Or you can try the ftp options of rpm :-)
