Well, it's the experience of many years (ca. a decade) of building RTEMS 
and GCC toolchains.

Also, I meanwhile me having re-added rtems-ada to the RTEMS source-tree 
some years ago (code OAR had abandoned), to be a personal mistake of 
mine. Otherwise, RTEMS Ada would have been dead for many years.

rpms finally has been ironed out in GCC ... other still persist.

Please try, building gcc-4.4.0 w/ Ada enabled on older systems, ... it's 
great fun. ... My patience with GCC Ada is over!
