I would like to debug Inkscape on Windows but given the lack of response here, I want to try a different approach.

It is possible to debug a linux application on Windows using Visual Studio and WinGDB. However, they only support Make, not Btool. 

I asked WinGDB for support and this was their reply:

///////////////
WinGDB can work with other build systems than make, but
project generation is supported only for make. You should
be able to build and debug, though.

You need to change default command lines from 'make' calls
to something suitable to build system used. Please consult
following sections of the documentation:

http://www.wingdb.com/docs/pages/wg_dev_mingw.htm
http://www.wingdb.com/docs/pages/wg_remotebuild.htm

We are not familiar with 'btool' build system, so you need to
find out how to call it in order to perform build and clean tasks.

Anyone know what the btool commands are equivalent to make?
