There is no need to add a new environment variable for this. The MAKEFLAGS variable already exists, and you can just add -I options into it which will be parsed as if you'd entered it on the command line. Also it's already possible when building GNU make on Windows to set the INCLUDEDIR preprocessor variable to add a new default pathname to GNU make: this just isn't done by default because there's no good choice for what it should be.

I've retargeted this issue as a generic enhancement to allow setting the .INCLUDE_DIRS variable to change the search path.

Attached a patch (to read.c only) which might serve as a starting point for allowing an additional (hardcoded) default include path given in a Windows environment variable (proposed variable name: 'MAKELIBPATH').

Please note that the patch ignores multiple paths (delimited by ';') given in MAKELIBPATH, i.e. MAKELIBPATH should contain one path only.

Futher enhancement:

The solution above might be considered as an intermediate step to where all paths in .INCLUDEDIRS are searched for makefiles to be included - regardless of where the paths are defined. As of now paths provided by the '-I' switch on the command line and default paths are the only ones which are searched for include makefiles, while any paths added to .INCLUDEDIRS within a makefile are not searched.
