file that defines Bool This directory now uses chromium-config.mk, and the sequence of includes is: PluginMessageUtils.h (brings in chromium basetypes and then nscore stuff) cairo-xlib.h QWidget QKeyEvent Do some Qt headers need to be included between chromium and nscore? Is there a way we can make this less fragile?

It is better to not include anything before Qt headers. or write some special Qt include wrapper which will undef all possible defines which are breaking Qt includes before including actual Qt includes.

I moved the Qt headers to the top again, but I definitely want a better solution long-term.
