Running RTEMS configure script from Eclipse

[Chris Welch]

The thing is you don't need the .bat interface at all.  Forking it off via
bash right from the start gives you a much better way of doing things.  Set
up the base script as a bash shell script.  You don't need the whole cygwin
environment to do it.  Bash gives you a full scripting language even without
supporting commands such as sed, awk, grep, etc.  They help, but you don't
have to use them to do basic scripting

E.g.:

Instead of:

build.bat:

      @echo off
      rem The following sets the paths and environment.
      call AutoSetEnv.bat
      %1 %2 %3 %4 %5 %6 %7 %8 %9

Set up a bash shell file you'll start as:

c:\cygwin\bash.exe buildit.sh

buildit.sh
# The following set the paths and environment
export PATH="/bin:/usr/bin:... Whatever"

cd /cygdrive/c/projdir
make $1 2>&1 make.out

etc....

Other args are there as $2, $3 etc.

That way you can leverage bash as a scripting environment and get away from
the lame .bat stuff.  

.bat technology is over 20 years old.  Take advantage of the tools you've
got.

This is ok for your setup and will suite most users but some people end 
up with more than cygwin version on their machine and they often to do 
not play well together. The approach I outlined avoids such problems by 
not providing the cygwin configuration as a global setup.

The batch files are not provided as a way to script, rather a way to 
setup an environment for native Windows programs that do not know how to 
execute a shell script or any thing about cygwin to work. I found this 
to be important with a MinGW based set of tools.

An all Cygwin environment should allow just scripts to be used, how-ever 
I do not use cygwin so cannot say for certain.
