setenv running in bash from the MSYS2 distribution provided with Git For Windows fails because of $0 being evaluated to /usr/bin/bash :

$ echo 'export DJDIR="$(cd "$(dirname "$0")"; pwd)"/i586-pc-msdosdjgpp ; echo $DJDIR' > test.sh
$ cat test.sh
export DJDIR="$(cd "$(dirname "$0")"; pwd)"/i586-pc-msdosdjgpp ; echo $DJDIR

$ ./test.sh
/h/devel/djgpp/i586-pc-msdosdjgpp

$ source ./test.sh
/usr/bin/i586-pc-msdosdjgpp

Using ${BASH_SOURCE[0]} instead of $0 fixes the problem.

Had the same problem on a Debian server with bash "version 4.4.12(1)-release (x86_64-pc-linux-gnu)". Changed the $0 references to $BASH_SOURCE as indicated here:
