There are several warnings. We will try to match them with

/* { dg-warning "'f1' is deprecated .declared at .*.: Please avoid f1" "" } */

dg-test in dg.exp will match each of them with:

    foreach i ${dg-messages} {
        verbose "Scanning for message: $i" 4

        # Remove all error messages for the line [lindex $i 0]
        # in the source file.  If we find any, success!
        set line [lindex $i 0]
        set pattern [lindex $i 2]
        set comment [lindex $i 3]
        #send_user "Before:\n$comp_output\n"
        if [regsub -all
"(^|\n)(\[^\n\]+$line\[^\n\]*($pattern)\[^\n\]*\n?)+" $comp_output
"\n" comp_output] {
            set comp_output [string trimleft $comp_output]
            set ok pass
            set uhoh fail
        } else {
            set ok fail
            set uhoh pass
        }

where $dg-messages is a list of

"'f1' is deprecated .declared at .*.: Please avoid f1"

with different line numbers. The fist one will match all warnings
in $comp_output and more, which lead to many failures.
