Yes, it affects the current cvs code. The problem is - exactly as reported - that the include file foo.h is present but can't be compiled. As far as I understand it configure first tries to locate the file foo.h and then tries to compile the small test program: /* All acdefines defined up to now */ /* Includes in the INCLUDE parameter */ #include <foo.h> Now, with sysv-based include files this would just tend to work but when you have a BSD-style include file then you have to list all prerequisites explicitly. As an example the attached patch to configure.in fixes all the warnings on AIX 5.2 but I do not want it applied yet as it messes up configure.in way to much. /MF
