            Bug ID: 26965
           Summary: clang should support -I= syntax
           Product: clang
           Version: trunk
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P
         Component: Driver
          Assignee: unassignedclangbugs at nondot.org

Since GCC 4.3 gcc has supported prefixing include paths with the sysroot. If
the -I option starts with '=', the '=' is replaced by the sysroot prefix,
either the one provided by --sysroot, or if both --sysroot and -isysroot are
used then the one provided by -isysroot.

Similarly, the linker search path supports -L=. But I suspect that's binutils
ld itself and not the gcc driver.
