Changed paths: M platforms/Cross/vm/sq.h

Log Message: ----------- Listen to feature_test_macros(7) with a guard.

If HAVE_CONFIG_H is given (most presumably on the command line) it is safe to include the (#define-only) config.h. On prominent platforms, these defines must precede any inlcudes. To quote feature_test_macros(7) on Linux:

NOTE: In order to be effective, a feature test macro must be defined before including any header files.

config.h provides these macros, either manually specified or through means of configuration (eg. autoconf/configure).

Having these defines early does not hurt platforms not using this system but is vital on platforms using it.
