I explicitly have a
set CYGWIN=
in the .bat file that initially invokes bash.
I do not set CYGWIN= elsewhere (just grep'd for it).

I change my test script to show empy CYGWIN=
$ cat tmq.sh
#!/bin/sh

export MQSERVER='BROWSE/TCP/mvs1(1414)'
echo CYGWIN=$CYGWIN
amqsbcgc Q

$ ./tmq.sh
CYGWIN=

AMQSBCG0 - starts here

 MQCONNX failed with CompCode:2, Reason:2539
