Many of the vendor tool chains are now (or soon will be) gcc and Eclipse
based. It's very common to do "closed source" code on open source based

According to the web page
the code is written in "Microsoft Quick Basic 3.2 compiler syntax".
So it is not an open-source tool chain.
I'm not sure what you mean by "OpenSource tool chain", but if you are
thinking of gcc, then there is a special GCC RUNTIME LIBRARY
so you can use gcc to create closed-source software, despite the fact
gcc is a GPL program.
As a reader of the gcc mailing lists, it is a fairly common question
on there, from people who want to use gcc for closed-source software,
but are not sure if it legal to do so. The answer is yes, you can use
gcc for commerical closed-source software.
