That is how I would do it as well, so we could start with various defines files if interested.

my opinion is that the os-specific-headers.h file is fine.  it's working, is a single file that works for all 3 major operating systems, and is clean.

for me, the only things that should go in a separate defines files should be locations of libraries and headers and compilers.
