Date: Fri, 29 Feb 2008 16:50:47 -0600

Package: libpt-1.11.2-dev
Severity: important
Version: 1.11.2-1.1
User: debian-release@lists.debian.org
Usertags: goal-dash

Hello maintainer,

While performing an archive wide checkbashisms (from the 'devscripts' package) 
check I've found your package containing a /bin/sh script making 
use of a bashism.

checkbashisms' output:
> possible bashism in ./usr/bin/ptlib-config line 50 ($(OS|MACH)TYPE):
>       echo $MACHTYPE
> possible bashism in ./usr/bin/ptlib-config line 53 ($(OS|MACH)TYPE):
>       echo $OSTYPE
> possible bashism in ./usr/bin/ptlib-config line 73 ($(OS|MACH)TYPE):
>       echo MACHTYPE     = $MACHTYPE
> possible bashism in ./usr/bin/ptlib-config line 74 ($(OS|MACH)TYPE):
>       echo OSTYPE       = $OSTYPE


Not using bash as /bin/sh would lead to errors or unexpected behaviours. 
Please be aware that although 
bash is currently the default /bin/sh there's a release goal for Lenny to 
make dash the default /bin/sh[1].

If you want more information about dash as /bin/sh, you can read:

[Message part 1 (text/plain, inline)]

This is a false positive.

OSTYPE and MACHTYPE variables are defined inside the script. And they 
are initialized on a portable way AFAIK (make/unix.mak):

ifndef OSTYPE
OSTYPE := $(shell uname -s)
endif

ifndef MACHTYPE
MACHTYPE := $(shell uname -m)
endif
