const can't be assigned to non const?

[homer_3]

I'm compiling ACE and get this error value of type "const SSL_METHOD *" can't be assigned to entity of type "SSL_METHOD *". Why won't C/C++ allow assigning a const value to a non const? Any ways to get around this without digging through the code and changing all the methods returning a const SSL_METHOD * to return a SSL_METHOD * ?
