Since I got no problems with -Wl,-Bsymbolic for ODBC I added for
dblib/ctlib too... Try to remove this option from Makefile.am... It's
strange linker did not find free/malloc and others libc functions...
I added also -export-symbols-regex option (it's a libtool option, not a
linker option). This option limit symbol exporting. It's used to
privatize unwanted symbols. My aim is to limit all tds stuff for
dblib/ctlib so to avoid future library incompatibility due to libTDS
changes or header changes.
