I have a problem I hope some-one can help me solving.

When executing a BASH script from the BASH shell (B19) on my Windows95
PC, I get extra end of lines on a BASH "read" command..

So, in a script like
  

echo -n "[Var 1] : "
read var1
echo -n "[Var 2] : "
read var2
echo -n "[Var 3] : "
read var3
echo -n "[Var 4] : "
read var4
echo " Var 1 = $var1 ; Var 2 = $var2"
echo " Var 3 = $var3 ; Var 4 = $var4"
 

I fail to enter data for $var2: when entering a response to the first read,
I seem to generate an extra <CR><LF> that is read on the second query.
The second "read" for $var2 is "automatically" answered, and $var2
is effectively empty.

I can then again enter a response for $var3; and get an extra <CR><LF>
to leave me with an empty $var4.

I tried terminating a response with just CTRL-J, but this did not solve the issue.

When executing the same script under Linux/Bash rather than Win95/Cygwin bash,
it runs OK.

I scanned the mailing list archive, and found this question being
asked several times, but I could not find a solution.

Can anyone please help me in this? The problem as it is prevents me
from eg. executiong "sh configure" scripts, which is quite annoying.

Thanks in advance !
