PHP/CODBC, undefined reference to `blablabla'

Please help!
i NEED to compile PHP 4.1.1 with custom-odbc (sybase in this case).
compile script:
--------------------------------
rm ./config.cache
make clean
export CFLAGS=-DODBC_UNIX
export LDFLAGS=
export ODBC_LIBS="L/usr/local/sybase/lib -lodbc"
./configure --with-custom-odbc=/usr/local/sybase
make
-----------------------------------
it all works fine with php 4.2.2 but
php 4.1.1 i get error:
-----------------------------------
/bin/sh /usr/src/php-4.1.1/libtool --silent --mode=link gcc -I. -I/usr/src/php-4.1.1/ -I/usr/src/php-4.1.1/main -I/usr/src/php-4.1.1 -I/usr/src/php-4.1.1/Zend -I/usr/src/php-4.1.1/ext/mysql/libmysql -I/usr/local/sybase/include -I/usr/src/php-4.1.1/ext/xml/expat -I/usr/src/php-4.1.1/TSRM -DODBC_UNIX -o php -export-dynamic stub.lo libphp4.la

./.libs/libphp4.a(php_odbc.o): In function `safe_odbc_disconnect':
php_odbc.o(.text+0xe5): undefined reference to `SQLDisconnect'
...etc
------------------------------------
..i tried to check header files but they look fine.
any suggestions?

looks like lodbc was not found...
manually added line to config.status
solved the problem.
