dnl ---------------
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
+dnl In particular, it addresses the problem of being able to run the C
+dnl preprocessor in a consistent manner.
+dnl
+dnl Caveat: this also disallows blanks in the pathname for the compiler, but
+dnl the nuisance of having inconsistent settings for compiler and preprocessor
+dnl outweighs that limitation.
