Hello,
I'm using
gcc version 4.3.1 20080507 (prerelease) [gcc-4_3-branch revision
135036] (SUSE Linux)
and I'm curious about the fact that gcc does not complain when giving
invalid directories as -I parameters, like:
# gcc -Wall -Wextra -I /nonexistent test.c
test.c:1: warning: unused parameter ‘argc’
test.c:1: warning: unused parameter ‘argv’
Shouldn't gcc warn (or fail) about the inexistent directory?
Regards.

-Wmissing-include-dirs (C, C++, Objective-C and Objective-C++ only)
Warn if a user-supplied include directory does not exist.
