On a Windows 9X system, environment variables are commonly configured in AUTOEXEC.BAT using the "set" command. The set command automatically uppercases the variable name - so adding "set MyValue=5" to autoexec.bat will result in an environment variable whose name is MYVALUE (as will running the set command from the CMD prompt). There are two variables - windir and winbootdir - that are lower-case on a Windows 98 system. Using my patch, I was able to run a shell and see that these variables remain lower-case in the shell environment, and that this didn't create any problems with any of the Cygwin utilities I tried. I could have written a program that would do a variety of SetEnvironmentVariable() calls using mixed-case variable names, and then would execute bash, but didn't go to those lengths. I don't believe this patch will have any adverse side-effects on a Win9X box. Ernie Coskrey SteelEye Technology, Inc.
