 You can disable whole classes of algorithms on the command line with the LTC_NO_* defines.  From there you can manually turn on what you want to enable.  
 
-The following build with GCC 3.4.3 on an AMD64 box gets you AES, CTR mode, SHA-256, HMAC, Yarrow, full RSA PKCS #1, PKCS #5, ASN.1 DER and MPI in 
-roughly 80KB of code.

+Obviously this won't get you performance but if you need to pack a crypto lib in a device with limited means it's more than enough...
 
 Neato eh?
