No. Perhaps it only does this for actions? If you change the line in my
example to something like:

VERSION_STRING = $(shell \this\path\does\not\exist\cat $(VERSION_TXT))

you get this error message
process_begin: CreateProcess(NULL, \this\path\does\not\exist\cat
file.txt, ...) failed.

which shows clearly that make is trying to execute cat directly.

I've tried that and it crashes too.

I then realised that the unique thing about my setup is that I'm
building with VS 2005, so I recompiled make with VS 2003 and the crash
no longer happens. I would suggest, therefore, that the version of
'close' in the  C runtime shipped with VS 2005 is stricter about
checking its arguments, which is why I see it and you don't.
