* cnv_tkt_skey.c, conv_creds.c, conv_princ.c, encode.c, sendmsg.c: Removed Mac-specific includes. * conv_creds.c: If we are on the Mac and using the CCAPI, set the string_to_key type to MIT. * krb524.h: Removed enumsalwaysint because there are no enums in this header.  Also include krb524_err with <> because on Mac OS X both are public headers and should not be included with "". * Makefile.in: set KRB524_PRIVATE while building so that Darwin builds see these prototypes.  Otherwise the Darwin build will fail
