All this sounds like code rott.

In previous versions of RTEMS, c/src/tests/support/include/tmacros.h had
been globally installed, with current RTEMS it isn't anymore. 
However, tmacros.h still should be installed to the "preinstall tree"
inside of RTEMS build-tree.

I recall having seen this quite a while back.

IIRC, the origin was a bug in arm-rtems-gcc, which I thought was fixed
by gcc-3.2.3-rtems patches.

Which gcc are you using? Vanilla gcc-3.x probably won't work.

Do the tests/samples compile? If yes, comparing the calls to gcc there
and in your case probably will help.
