hostapd compilation problems - `MD5_DIGEST_LENGTH' undeclared

[Prj 2004]

Friends,

I am trying to compile hostapd 0.3.7 and have the below .config

----
CONFIG_DRIVER_WIRED=y
CONFIG_DRIVER_MADWIFI=y
CFLAGS += -I../usr/local/src/madwifi # change to reflect local setup; directory for madwifi src

CONFIG_IAPP=y
CONFIG_RSN_PREAUTH=y
CONFIG_EAP=y
CONFIG_EAP_MD5=y
CONFIG_EAP_TLS=y
CONFIG_EAP_MSCHAPV2=y
CONFIG_EAP_PEAP=y
CONFIG_EAP_GTC=y
CONFIG_EAP_TTLS=y
CONFIG_EAP_SIM=y
CONFIG_PKCS12=y
----

I get several errors (and some warnings too) when the compiler (gcc 2.95) hits radius.c as below:

Can someone please correct me what's being done wrong?  Am I missinging any MD5 or Crypto dependencies?

TIA
