DejaGnu cannot routinely strip escape sequences because they could be 
part of the intended output---or strictly forbidden in the intended 
output.  Further, I suspect that the comparison is being carried out in 
the testsuite code rather than the framework, but the thread that 
arrived on the DejaGnu list does not mention what test is failing or 
what testsuite is being run.  Based on the inclusion of 
fortran@gcc.gnu.org, I am guessing this is an issue with the GNU Fortran 
tests.

This is either a testsuite problem or an environment problem.  The GNU 
Fortran I/O module certainly has interesting behavior here.  Try setting 
TERM=dumb in the environment while running the testsuite.  If that fixes 
the problem, it may be appropriate to add "set ::env(TERM) dumb" to the 
tool init file for GNU Fortran.
