shared libraries with the @code{--disable-shared} option to configure.
Some customers have had problems on BSDI 4.0.1 that the @code{mysqld}
binary after a while can't open tables. This is because some
library/system related bug causes @code{mysqld} to change current
directory without asking for this!
The fix is to either upgrade to 3.23.34 or after running @code{configure}
remove the line @code{#define HAVE_REALPATH} from @code{config.h}
before running make.
Note that the above means that you can't symbolic link a database directories
to another database directory or symbolic link a table to another database
on BSDI! (Making a symbolic link to another disk is ok).
