Can gcc restrict certain warnings to exclude certain files or to apply

-Wconversion, and some others to apply only to my own code, and not
(say) boost headers. (I do use -Werror.) Thanks in advance.
You can ignore warnings from headers that are not your own by using -isystem
instead of -I.

Thanks, this led me to one fix. I was previously using CPATH for
indicating where to find my system files. However, CPATH gets treated
as -I. I'm now using CPLUS_INCLUDE_PATH/C_INCLUDE_PATH, which get
treated as -isystem and don't lead to warnings.
I'm also working on a common C++ header library that's included by
several of my projects; this is found on the system path, and it would
be nice if I could enable warnings for these. Still, -isystem is a
major improvement over the prior situation.
