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
dnl with 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.

dnl ---------------
dnl Determine the default configuration into which we'll install ncurses. This
dnl can be overridden by the user's command-line options. There's two items to
dnl look for:
dnl 1. the prefix (e.g., /usr)
dnl 2. the header files (e.g., /usr/include/ncurses)
dnl We'll look for a previous installation of ncurses and use the same defaults.
dnl
dnl We don't use AC_PREFIX_DEFAULT, because it gets evaluated too soon, and
dnl we don't use AC_PREFIX_PROGRAM, because we cannot distinguish ncurses's
dnl programs from a vendor's.
