My suggestion is that you can implement it as an optional command line
option(like -j), and on one or two primary platforms(Linux/Windows),
instead of on all platforms.
So, the complexity of both possibilities.

Hi,
Serialisation can be done by external programs - no real need for make to do it.
My project does it already with the talon shell wrapper that we use in
our build system here:

We have to ensure that these temporary files are cleaned up properly,
even in the face of users ^C'ing their make invocations. We also need
to verify that whatever methods we use will work properly

The use of semaphore may impair performance.

This seems like quite an extreme example. stdout is line buffered by
default,
on half-way decent systems - and even then, I'm not sure, it might be
limited to when writing to a TTY.
I use make -j 4 to build and test gcc, the situation above is very common.

Never mind.
The problem is that the variables are already expanded, and the functions

If by already expanded ... when the template is being defined you mean
