// e10s mess: IPDL-generated headers include chromium files that both #include
// prlog.h, and #define LOG in conflict with this file.
// Solution: (as described in bug 545995)
// 1) ensure that this file is #included before any IPDL-generated files and
// anything else that #includes prlog.h, so that we can make sure prlog.h
// sees FORCE_PR_LOG
// 2) #include IPDL boilerplate, and then undef LOG so our LOG wins.
// 3) nsNetModule.cpp does its own crazy stuff with #including prlog.h
// multiple times; allow it to define ALLOW_LATE_HTTPLOG_H_INCLUDE to bypass
// check.
