RE: [cdt-dev] Order of User-defined and Built-in includes/macros(was:How to get CDT parser to search -I includes before defaultincludes)

Ok, looks like everyone agrees to the proposed order. I'm going to make
this change.
If someone disagrees please speak up.

Yup, a quick gcc -v shows the user includes come first.

I'm pretty sure that gcc always searches the user-specified -I
directories before any built-in ones. However, I'm also pretty sure
that the behavior is compiler dependent (see Leo's post), and therefore
no single assumption by MBS will be correct for all compilers. Also
this seems like a familiar topic? Maybe this was discussed on the list
in the past sometime.
