autoconf-2.57 WARNING from AC_CHECK_HEADERS for X11/Xaw/Text.h

[John Ellson]

I'm getting this message when trying to test for any header file in X11/Xaw/


checking X11/Xaw/Text.h presence... yes
configure: WARNING: X11/Xaw/Text.h: present but cannot be compiled
configure: WARNING: X11/Xaw/Text.h: check for missing prerequisite headers?
configure: WARNING: X11/Xaw/Text.h: proceeding with the preprocessor's 
result
configure: WARNING:     ## ------------------------------------ ##
configure: WARNING:     ## Report this to address@hidden ##
configure: WARNING:     ## ------------------------------------ ##
checking for X11/Xaw/Text.h... yes




This is from AC_CHECK_HEADERS with autoconf-2.57  on Solaris-8

I think X11/Intrinsic.h is a prerequisite.  I've  I have 
-I/usr/include/X11 in $CPPFLAGS
but perhaps I need to do something else for prerequisites?
