One way of looking at this (which gets mentioned on the autoconf list
whenever it comes up) is that AC_CHECK_LIB isn't very useful, since it
always links against the libraries listed in the `other libraries'
argument. Erez Zadok has a version (called AC_CHECK_LIB2) of this macro
that instead only adds the other libraries to LIBS if the initial test
fails but it then succeeds with the other libraries.
I think this is probably what we want, but I may have misunderstood the
problem because of the rather fractured beginning of the thread.
Could someone with one of these `-lmysqlclient requires -lz' systems
test this? You need to apply the diff below and add:
http://iw3d.co.uk/~mark/check_lib2.m4
... in the config directory.

P.S. Sorry for taking so long to reply, I suddenly noticed I had 50
