Summary: Hardcoded modules.lst path breaks on non-root install

Initial Comment:
***

Problem #1:
What: Hardcoded search path for file "modules.lst"
breaks when performing a user (non-root) install of the
library or simply using a different install prefix.

Where: The source file "src/unix/umodules.c" at line 47
defines the path where to find the file "modules.lst"
at runtime.

@src/unix/umodules.c:44
--------------- begin code snippet ---------------
/* where to look for modules.lst */
static char *module_path[] =
{
   "/usr/local/lib/allegro/", "/usr/lib/allegro/", NULL
};
--------------- end code snippet ---------------


Possible Fix: Apply a variable that corresponds to the
install prefix determined by the user at compilation.

***

Problem #2:
What: The ending slash of the paths defined on the
above code snippet is not necessary as it results in
code containing double slashes in the search path for
"modules.lst". Example:
"/usr/local/lib/allegro//4.2/moules.lst".

Possible Fix: Remove ending slashes from the coded paths.

***
This was identified running
strace MyAllegroProgram 2>&1|egrep "(modules.lst)"
on an Ubuntu 5.10 Breezy box as a standard user (non-root)

This issue was already identified by a NetBSD user @
