Greetings,
First of all please note that I was using the SunStudio-12 compiler
and not GCC for this. I'm sorry if I was not clear on that point.
If I use GCC however I do not get any complaint about the operator
overloading. It ends up like this.

With Sun C however after commenting out the line you suggested, it
ends up like this....

Two very different types in C++).This might be a Squid bug. I am not an
expert on this, but I am notsurprised that GCC is confused by the halfway migration from method_tenum to HttpRequestMethod class.There are no pointers involved here. The global "!=" operator on line138 provides comparison between a [reference to] HttpRequestMethod and amethod_t. There is also a constructor that can create anHttpRequestMethod from a method_t. Method_t is an enum, so it is treatedlike an int in many contexts.Thus, when we write "5 != 6", GCC may not know whether he is supposed tocreate an HttpRequestMethod from 5 and method_t from 6 to use the customoperator or just go with the built-in operator for integer comparison.Remove the global operator != at line 138 of HttpRequestMethod.h andSquid may compile. It does in my test, but I did not have the aboveproblem to start with so YMMV. Please keep me posted as I would like tocommit this fix if it works for you.Thank you,Alex.
