MoonchildProductions#1251 - Part 16: Resolve namespace conflicts with dbm on Solaris.
https://bugzilla.mozilla.org/show_bug.cgi?id=1513913 Mozilla's solution to this is arguably overkill, since the namespace issue on Solaris only required them to change (or temporarily undefine) __log2. Instead they changed ALL the functions to be something along the lines of dbm_log2. They haven't changed the external interface at all, though. If you're unhappy with this patch, I think I could also use XP_SOLARIS ifdefs to undefine __log2 prior to where it's declared in the dbm headers. The good thing about Mozilla's solution is that it guarantees this namespace issue never occurs again on any platform, though.
