I needed to patch /usr/share/dejagnu/target.exp to ignore
-ffunction-sections warnings.

Just under the lines "# Cygwin cc1 warns about -fpic" add


    # Cygwin gcc warns about -ffunction-sections
    regsub -all ".*: warning:
-ffunction-sections\[^\n\]*\n\[^\n\]\[^\n\]*may affect debugging on some
targets." $text "" text


making sure that the regsub is a single line - my mailer will mangle it :-(
