Would you please send a patch? If it works well, I'd like to take it.

Because I don't want to make gtags.conf for each OS. '.so' is not a common
extension. But now rereading the libtools manual, I have found
lt_dlopenext()
function. Using this, we can load library without extension.
[derived from libtool manual]
-----------------------------
@deftypefun lt_dlhandle lt_dlopenext (const char *@var{filename})
The same as @code{lt_dlopen}, except that it tries to append
different file name extensions to the file name.
If the file with the file name @var{filename} cannot be found
libltdl tries to append the following extensions:
@enumerate 1
@item the libtool archive extension @file{.la}
@item the extension used for native dynamically loadable modules on the
host platform, e.g., @file{.so}, @file{.sl}, etc.
@end enumerate
-----------------------------
I will rewrite dynamic loading code using this. It will be like follows:
if (lt_dlopen('foo.la') == FAILED)
if (lt_dlopenext('foo') == FAILED)
error_and_exit();
This code should work without '.la' files.
Thank you for giving me a chance of re-investigation.
