That patch was only meant to deal with the 32K command line length limitati=
on
on Windows hosts, for programs spawned with the pex functions (to my knowle=
dge,
this is how the driver spawns its sub-programs like the compiler, assembler=
 and
linker).

In this PR though the problem appears to be something else which I am not
familiar with, so I don't know if its going to be helpful to see that patch=
 as
a guide.   I only put the reference in the hopes that it solved this as well
because it looked similar, but it doesn't look like it.    You may need to =
come
up with a completely new solution for all I know.=
