Firstly, I don't know why you are doing 'include gmsl'.  You don't need 
it for what you are trying to do.

Secondly, your use of $(if) is incorrect.  Since the entire line 
starting $(if) will be expanded before any of the commands for all are 
run the value of status is irrelevant and the result you'll get will be 
based on the value of status in the Makefile.

What you really want to do is something like this:

all:
        @myprogram
        @if errorlevel 1 ( echo failed ) else ( echo success )
