Problem with shell commands on Digital UNIX V4.0F.

[Matt Hodges]

I'm having problems building a program on Digital UNIX V4.0F, and it
seems to boil down to the following observed behaviour on this
platform. The results from issuing `make' with this makefile:

----------------------------------------------------------------------
FUBAR=$(shell echo fubar)

all:
        @echo FUBAR = $(FUBAR)
----------------------------------------------------------------------

are:

Version         Result

3.78.1          FUBAR = fubar
3.79.1          FUBAR = fubar
3.80            FUBAR =
3.81a1 (CVS)    FUBAR =

whereas on alpha/Linux (and I guess other platforms), version 3.80
behaves the same as 3.78.1 and 3.79.1 above.

Any help, pointers, or suggested workarounds appreciated.

Thanks,
