I also see this. Looks OK:
Users use many different shell programs, but commands in makefiles
are always interpreted by `/bin/sh' unless the makefile specifies
otherwise. *Note Command Execution: Execution.
The shell that is in use determines whether comments can be written
on command lines, and what syntax they use. When the shell is
`/bin/sh', a `#' starts a comment that extends to the end of the line.
The `#' does not have to be at the beginning of a line. Text on a line
before a `#' is not part of the comment.
