Debugging tools and practices in Windows?

Hello r-devel, could someone share the tools and practices they use to
debug the core R sources in Windows?

For instance, I would like to set a breakpoint in `gl_loadhistory` and
troubleshoot from there.

You're talking about debugging the C code rather than the R code, I think.

These days I mostly avoid debugging in Windows, but when I have to do 
it, I use gdb.  There used to be a front end for it (Insight) that 
worked in Windows, but I don't think it works with our current gdb 
build.  Google names lots of other front ends, but I haven't tried any 
of them in Windows.

The other choice is the old fashioned method:  add lots of Rprintf() 
statements to the source and recompile.
