Description
When cross-compiling on a older host (CentOS 5, for example):
| cc1: error: unrecognized command line option "-Werror=implicit" | cc1: error: unrecognized command line option "-Werror=nonnull" | cc1: error: unrecognized command line option "-Werror=init-self" | cc1: error: unrecognized command line option "-Werror=main" | cc1: error: unrecognized command line option "-Werror=missing-braces" | cc1: error: unrecognized command line option "-Werror=sequence-point" | cc1: error: unrecognized command line option "-Werror=return-type" | cc1: error: unrecognized command line option "-Werror=trigraphs" | cc1: error: unrecognized command line option "-Werror=array-bounds" | cc1: error: unrecognized command line option "-Werror=write-strings" | cc1: error: unrecognized command line option "-Werror=address" | cc1: error: unrecognized command line option "-Werror=int-to-pointer-cast" | cc1: error: unrecognized command line option "-Werror=pointer-to-int-cast"
Whilst the configure script checks the warning options it only does that for the cross compiler and not the host compiler (used when building makekeys).
