Subject: Re: Unused global symbols in jumbo
Many of these have to be global. There were issues in some compiling env's (cygwin??) where it would not align static variables. Thus, we have #defines in each source, which mangles the normal name (crypt) into something unique to the format (MD5Gen_crypt, etc). Yes, they are globals, but steps have been taken to make sure they are linker safe.
There is little/no gain worrying about unused globals. The only time it matters at all, is at link time. The linker will tell you if there are problems.
