Details:
The NEWS file says:
Version 3.81
* WARNING: Backward-incompatibility!
Some previous versions of GNU make had a bug where "#" in a function
invocation such as $(shell ...) was treated as a make comment. A
workaround was to escape these with backslashes. This bug has been
fixed: if your makefile uses "\#" in a function invocation the
backslash is now preserved, so you'll need to remove it.
But I still get that bug with 3.81 and with CVS HEAD. The following
makefile:
FOO:=$(shell echo '#')
foo:
echo '$(FOO)'
gives:
Makefile:1: *** unterminated call to function `shell': missing `)'. Stop.
while
FOO:=$(shell echo '\#')
foo:
echo '$(FOO)'
works, and the backslash is _not_ passed to the shell.
