The problem I had with AC_SEARCH_LIBS was that if I don't add all of the
libraries (-lasn1 -lroken etc.) the test program won't compile, even
though the .o compiles fine. Can we make the test only depend on
generating a .o?

I'd like to make it a bug fix for 7.2 if we can, so I'd appreciate the
help. I can test any new versions of the patch. :-)

Oh, I'll be out of town from Nov 19 through the 24th, and I have
intermittent weekend EMail, so please understand if I am less than
responsive in those time windows. :-)

Take care,

Bill
