Subject:	cygwin-bash compat/regression bug... startup line prob
X-IsSubscribed:	yes

This 'used' to work...but doesn't now: -- running
bash with the "-u" flag:

> t.sh
/usr/bin/bash: - : invalid option
Usage:  /usr/bin/bash [GNU long option] [option] ...
         /usr/bin/bash [GNU long option] [option] script-file ...
GNU long options:
         --debug
         --debugger
         --dump-po-strings
         --dump-strings
         --help
         --init-file
         --login
         --noediting
         --noprofile
         --norc
         --posix
         --protected
         --rcfile
         --restricted
         --verbose
         --version
         --wordexp
Shell options:
         -irsD or -c command or -O shopt_option          (invocation only)
         -abefhkmnptuvxBCHP or -o option
> which t.sh
/Users/law.Bliss/bin/t.sh
> cat bin/t.sh
#!/bin/bash -u -x
echo "Hello World"
>
-----------------------------

It has something to do with the "-u" switch -- the "-x" was
added to try to figure out why a script that had just
#!/bin/bash -u
died w/o executing a single line.

If I run it via:
> bash t.sh
Hello World
>
---works---
Also weird -- the interp line says "/bin/bash" not "/usr/bin/bash"
as the shell, so why does the error come from /usr/bin/bash?

It doesn't when I do it interactively:
> /bin/bash - - 
/bin/bash: -: No such file or directory
---
or 'bash' alone:
> bash - - 
bash: -: No such file or directory


----
Ideas?  would a cygcheck be of any use?

Note, if I combine the switches (-ux), it works -- but I only
added the '-x' to debug why '-u' didn't work.

GNU bash, version 4.1.11(2)-release (x86_64-unknown-cygwin)

This, also, doesn't work:
> echo t.sh|bash -i     #(with or without '-i')
#note -- first some unrelated output from confused startup scripts:

## here is the 'echo' being read into bash:

law.Bliss> t.sh
