Summary:                    Enumerated type and integer comparison do not work
as you might expect
Description: 
In main/channel.c there is a section of code (about line 2530):
+        if (condition < 0) {
+                /* Stop any tones that are playing */
+                ast_playtones_stop(chan);
+                return 0;
+        }

Where "condition" is an enumerated type. It seems logical that you can
compare ordinal position of the value of variable (which is a number) to an
integer, but it does not work. If the integer value of condition is -1 then
the statement should evaluate as should be "true", but does is not (at
least on my system). If you change the code to cast "condition" as an
integer:
+        if ((int)condition < 0) {
then the comparison works as expected.
