FWIW i've noticed that with make 4.0/4.1 built for Win32, invoking the
Cygwin bash shell as C:/cygwin/bin/sh.exe, the command lines are
silently truncated at ~8K characters - this did not happen when we used
GNU make 3.82 built for Cygwin.

i haven't investigated where exactly that happens, the documented Win32
CreateProcess maximum command line length is 32k characters.
