Fix for Accepted by compiler / rejected by the preprocessor issue ?

Users in the past have reported this behavior with autoconf 2.57-3:

checking X11/Xft/Xft.h usability... yes
checking X11/Xft/Xft.h presence... no
configure: WARNING: X11/Xft/Xft.h: accepted by the compiler, rejected by
the preprocessor!
configure: WARNING: X11/Xft/Xft.h: proceeding with the preprocessor"s
result
configure: WARNING:     ## ------------------------------------ ##
configure: WARNING:     ## Report this to [email protected] ##
configure: WARNING:     ## ------------------------------------ ##
checking for X11/Xft/Xft.h... no

I don't know much about autconf, but the issue seems to be that 
xft-config --cflags gets passed as CFLAGS in configure, but not 
CPPFLAGS, and autoconf tries to compile with both the preprocessor and 
the compiler.

If you've had this problem, you can try this patch against CVS and see 
if it works for you.
