I think that you can just drop the final _win suffix.
Unforuntately, as you might have found out, you cannot benefit of the auto
exclusion rule (which excludes *win.cc on Non-win platforms) if you are in a
gypi file.
...at which point i'd just make call just winheap_dump_provider.

It looks like I can just use the _win suffix and get rid of the condition
(https://code.google.com/p/gyp/wiki/GypUserDocumentation#Add_a_platform-specif...)

You probably want the same conditional logic  here? (or just move the conditions
block above in lines 46-58 to the end, so you can use the same OS==win condition
to augment both trace_event_sources and trace_event_Test_sources

Ditto.
