+# AC_MSG_NOTICE([The option is supported])],[
+# AC_MSG_NOTICE([No luck this time])
+# ])
+#
+# The macro doesn't discriminate between languages so, if you are testing
+# for an option that works for C++ but not for C you should use '-x c++'
+# as EXTRA-OPTIONS:
+#
+# AX_GCC_OPTION([-fno-rtti],[-x c++],[],[ ... ],[ ... ])
+#
+# OPTION is tested against the following code:
+#
+# int main()
+# {
+# return 0;
+# }
+#
+# The optional TEST-PROGRAM comes handy when the default main() is not
+# suited for the option being checked
+#
+# So, if you need to test for -fstrict-prototypes option you should
+# probably use the macro as follows:
+#
+# AX_GCC_OPTION([-fstrict-prototypes],[-x c++],[
+# int main(int argc, char ** argv)
+# {
+# (void) argc;
+# (void) argv;
+#
+# return 0;
+# }
+# ],[ ... ],[ ... ])
+#
+# Note that the macro compiles but doesn't link the test program so it is
+# not suited for checking options that are passed to the linker, like:
+#
+# -Wl,-L<a-library-path>
+#
+# In order to avoid such kind of problems you should think about usinguse
+# the AX_*_CHECK_FLAG family macros

+# SYNOPSIS
+#
+# AX_LIB_MYSQL([MINIMUM-VERSION])
+#
+# DESCRIPTION
+#
+# This macro provides tests of availability of MySQL client library of
+# particular version or newer.
+#
+# AX_LIB_MYSQL macro takes only one argument which is optional. If there
+# is no required version passed, then macro does not run version test.
+#
+# The --with-mysql option takes one of three possible values:
+#
+# no - do not check for MySQL client library
+#
+# yes - do check for MySQL library in standard locations (mysql_config
+# should be in the PATH)
+#
+# path - complete path to mysql_config utility, use this option if
+# mysql_config can't be found in the PATH
+#
+# This macro calls:
+#
+# AC_SUBST(MYSQL_CFLAGS)
+# AC_SUBST(MYSQL_LDFLAGS)
+# AC_SUBST(MYSQL_VERSION)
+#
+# And sets:
+#
+# HAVE_MYSQL

+# AX_LIB_POSTGRESQL([MINIMUM-VERSION])
+#
+# DESCRIPTION
+#
+# This macro provides tests of availability of PostgreSQL 'libpq' library
+# of particular version or newer.
+#
+# AX_LIB_POSTGRESQL macro takes only one argument which is optional. If
+# there is no required version passed, then macro does not run version
+# test.
+#
+# The --with-postgresql option takes one of three possible values:
+#
+# no - do not check for PostgreSQL client library
+#
+# yes - do check for PostgreSQL library in standard locations (pg_config
+# should be in the PATH)
+#
+# path - complete path to pg_config utility, use this option if pg_config
+# can't be found in the PATH
+#
+# This macro calls:
+#
+# AC_SUBST(POSTGRESQL_CFLAGS)
+# AC_SUBST(POSTGRESQL_LDFLAGS)
+# AC_SUBST(POSTGRESQL_VERSION)
+#
+# And sets:

+# SYNOPSIS
+#
+# AX_LIB_SQLITE3([MINIMUM-VERSION])
+#
+# DESCRIPTION
+#
+# Test for the SQLite 3 library of a particular version (or newer)
+#
+# This macro takes only one optional argument, required version of SQLite
+# 3 library. If required version is not passed, 3.0.0 is used in the test
+# of existance of SQLite 3.
+#
+# If no intallation prefix to the installed SQLite library is given the
+# macro searches under /usr, /usr/local, and /opt.
+#
+# This macro calls:
+#
+# AC_SUBST(SQLITE3_CFLAGS)
+# AC_SUBST(SQLITE3_LDFLAGS)
+# AC_SUBST(SQLITE3_VERSION)
+#
+# And sets:
+#
+# HAVE_SQLITE3
