Apple needs a command-line switch to the compiler which will change the lookup
of include files and
link libaries. The semantics would be something like:
-isystem-headers-and-libaries <pathname>
When this command line option is given to the compiler, all of the compiler's
builtin searching for
includes and libaries would start with <pathname> instead of with '/'. If a
file is included or linked with
and is not in the hierarchy given by <pathname> the compiler will return a
"file not found" error.
All other command line options related to include and link searching,
particular paths given by -I and
the like, would be unchanged.
This command line search is useful for Apple's compiler, where we would like to
build for other
versions of Darwin while running on a stable host. It could also be used in an
environment such as a
distcc farm, where the system headers for a target system are in a known
location, but the binaries on
the build system will work just fine to build the program.
