For easier understanding I reduced the problem to the following:
My list of files (let's say for simplicity they are all in the same
directory) comprises 500 files. Compiling in the source folder is no
Now I add an object path to the make rule to get the binaries in a
different folder.
When the object path exceeds 20 characters, make breaks with:

C:\DOCUME~1\go\LOCALS~1\Temp\make1636-1.bat, ...) failed.
make (e=87): The parameter is incorrect.
make: *** [PLATFORM/StarTarget7/OUT/lib/crtl/time/GETTMOD.d] Error 87

No difference when I use sh.exe as shell.

Thank you for your report.

Is it possible to show a short Makefile that can be used to reproduce
this problem?  It is very hard to try to debug a problem without even
the offending fragment of a Makefile to look at.

Btw, where did you get the binary of Make 3.81?

The binary was build by myself.
Find below a condensed makefile which I used for tests. I think that the dependency section is not necessary, it contains some special stuff for adapting .o to .obj by means of sed.
