 Looking at the patch (2.4.0-test2), yes.  magic and X86_FXSR_MAGIC
 where introduced at the same time.

 I agree with you, stopping in the middle of the compilation isn't nice.
 The problem is you can't run something while generating the Makefiles
 from the Imakefiles, can you?  You just need to check that:

#include <signal.h>

#if defined(SSE_CHECK) && !defined(X86_FXSR_MAGIC)
#error "X86_FXSR_MAGIC not defined"
#endif

 doesn't produce an error.
