I had no Solaris 10 to test it...  So what's the correct way to detect 
Solaris 10?

Solaris 9 behaves correctly if __MAKECONTEXT_V2_SOURCE is defined (it 
is defined in common.h).  I've tested this case.

The manual claims:
      The value of
      argc must match the number of integer  arguments  passed  to
      func, otherwise the behavior is undefined.
(SunOS mion 5.9 Generic_112233-12 sun4u sparc SUNW,Ultra-250)

I only pass single argument...

Who uses Solaris x86?
