 dnl Check for user's environment-breakage by stuffing CFLAGS/CPPFLAGS content
 dnl into CC.  This will not help with broken scripts that wrap the compiler with
 dnl options, but eliminates a more common category of user confusion.

+dnl In particular, it addresses the problem of being able to run the C

 dnl outweighs that limitation.
