Could not verify this with 4CVS-2002-07-31 on Compaq Tru64, so it seems not to be an 64Bit-Issue.

Do you have any testcases for this I can run to test if the extension is working as expected?

I've written some testcases for myself. They all seem to work fine.

do you still have this problem with current cvs-version?

Hmm, now the STABLE branch also gives an error, since today.

Seems that permissions are set without a read flag, resulting in a permission defined when linking.
autoconf 2.13, automake 1.5 and libtool 1.4.

I get this error when compiling php 4.3.0 or the cvs snapshot for today (jan 13th 2003) on AIX 5.2, sounds like the same error but the latest snapshot does not fix it.

gcc-2.9.aix51.020209-1
libtool-1.4.2-1
make-3.79.1-3
automake-1.5-1
autoconf-2.53-1
