Sorry, I checked again, it was not version 6. My CD is from
C++Builder 5.0.

Underfined weak symbols make it impossible to prelink a binary
because those symbols are only resolved at runtime. Also, you
cannot strip symbols from the main executable. And it is also not
possible to make real library wrappers: if I create a libfoo library
that links against allegro, I have to link the final program with
-lalleg_unsharable even if it only uses symbols from libfoo and not
allegro.
I believe it is much cleaner to have an allegro_set_icon() function
in the API than to depend on the presence of an allegro_icon symbol in
the main program.

That would be nice indeed, though I'd have done it the GTK+ way:
having allegro_init() accept argc and argv as arguments, or 0/NULL, so
that no ugly /proc parsing is necessary (on my grsec laptop, non-root
users cannot browse /proc except for specific cases).
