I already put in a default; see platforms/Cross/plugins/B3DAcceleratorPlugin/sqOpenGLRenderer.c

I see that here https://git.io/v9QbB
and the error disappears in

I found  _MAX_PATH in <stdlib.h>
at "Path Field Limits" for MSVC here...

but I'm not sure how that relates to Cygwin.  I see PATH_MAX defined
in "limits.h" here...
