           Summary: error: invalid switch '-x'
           Product: gcc
           Version: 3.3.1
            Status: UNCONFIRMED

When building GCC C and C++ with HP C A.05.50, the "make bootstrap" fails with:

error: error: invalid invalid switch '-x'
switch '-x'

I used no "configure" options and I have no version of GCC installed.
