And again a number of stupid unrelated quotes.
Just for the record, I mentioned this once already: dynamic linking
enters a lot of binary addresses into a program, making it an image
in memory that is completely dependent and "linked" with the library
in question. Calling dlopen from inside of a module to load a
library and call its functions explicitly instead of by linking
doesn't.
While this is a fine line, it is obviously thick enough to have caused
RMS to refuse letting a module loader (which would have used dlopen)
be put into Emacs because he thinks that in that case
Emacs/proprietary combinations could become more legally viable than
desirable.
Of course, on a typical system Emacs is dynamically linked with a
number of libraries already, but not via the "dlopen by program"
method.
