# LIBUNIXODBC_CHECK_CONFIG ([DEFAULT-ACTION])
# ----------------------------------------------------------
#
# Checks for unixodbc. DEFAULT-ACTION is the string yes or no to
# specify whether to default to --with-unixodbc
# If not supplied, DEFAULT-ACTION is no.
#
# This macro #defines HAVE_UNIXODBC if required header files are
# found, and sets @UNIXODBC_LDFLAGS@ and @UNIXODBC_CFLAGS@ to the necessary
# values.
#
# Users may override the detected values by doing something like:
# UNIXODBC_LDFLAGS="-lunixodbc" UNIXODBC_CFLAGS="-I/usr/myinclude" ./configure
#
# This macro is distributed in the hope that it will be useful,
# but WITHOUT ANY WARRANTY; without even the implied warranty of
