Hi all,
thanks for all interesting answers. Well, using the sysconf() function
looks like the smoothest way to do the job, even though it's not as
easily nested into autoconf as my dirty hack... how would you add the c
code to the program? can is be easily compiled while configure is
running und its output be used, e.g. via AC_TRY_RUN()?

cu, philipp
