Hi Hiroyuki, I've thought about it some more and tried the following (in the apr directory _without_ any changes to the apr_sms_threads.h file):
$ awk -f build/make_export.awk include/apr_sms_threads.h APR_HAS_THREADS apr_sms_threads_create apr_sms_threads_create_ex /APR_HAS_THREADS As you can see this produces the correct output on my box. I can't imagine that awk on FreeBSD is generating something different, but can you please check? Thanks, Sander
