Before we consider taking the value from an environment variable, IMO we should augment the default value to include the default places where MinGW is installed. Feature requests are better submitted as Savannah bug reports, see http://savannah.gnu.org/bugs/?func=additem&group=make Thanks. --- A feature request re (1) and (2) is posted (http://savannah.gnu.org/bugs/index.php?47880) including a patch which might serve a starting point for the implementation of option (1) above; here the Windows environment variable MAKELIBPATH is used. Just as a side remark: The standard installation path of MinGW is C:\MinGW to where I think some users might have restricted access only, if at all. Separately attached an enhanced version of build_w32.bat (incl. .diff against the current Savannah git version) allowing for MinGW compilation, as well. This is useful if - as here - MinGW and Cygwin exist in tandem on the system. Please note that the script includes the definition of hard coded explicit include paths (-D INCLUDEDIR = ...). Thanks, J.
