[MiNT] tw-call.app bug when toswin2.app is missing

[Vincent Rivière <vincent.riviere@freesbee.fr>]

Hello.

It seems that there is a bug in tw-call.app when toswin2.app is not found.
Look there, at the end of the find_tw() function:
http://sparemint.atariforge.net/cgi-bin/cvsweb/freemint/tools/toswin2/tw-call/tw-call.c?rev=1.7&content-type=text/x-cvsweb-markup

The code calls shel_write(1, 1, 1, ...) to run toswin2.app, then it assumes 
that the return value is the app_id. However, it seems that when toswin2.app 
is missing, the returned value is also non-null. Then things goes wrong.

Also, is that evnt_timer(500L) really useful?

Could some AES guru look at that code, please?
