It works ok on linux32. But for linux64, it needs the following patch for gcc apart from -m64 in Makefile
/* UINT4 defines a four byte word */ -typedef unsigned long int UINT4; +typedef unsigned int UINT4; 9!:29]1 - md5raw=: ((1!:43''),'/libmd5.so MD5String > i *c i')&(15!:0)@(;#) + md5raw=: ((1!:43''),'/libmd5.so MD5String > x *c i')&(15!:0)@(;#) May be the cc referenced by md5 rfc is very ancient.
