Crashing Firefox Goes libcurl

I guess I haven’t been paying attention lately, but I stumbled over the Breakpad project, which incidentally is gonna be used as crash reporting tool for Firefox 3, and it uses libcurl: “On Linux, libcurl is used for this function, as it is the closest thing to a standard HTTP library available on that platform.libcurl

The wording implies that it uses something else on Mac OS X, but I’m not aware of any standard HTTP library on it. Am I missing something or are they going libcurl there too?

Also, I wonder if using different HTTP libraries on different platforms instead of a single one isn’t just begging for more problems than what it solves? As far as I know, libcurl has a few upsides compared to wininet for example. Of course, I’m not the man to tell how they should do their stuff.
