Chris I do have Cygwin here and I cannot tell which grep Vim(windows version) uses to be honest, since I cannot get grep to print the platform but I believe it is the windows version from Windows Gnu utilities which has v 2.5 while Cygwin version is 2.6. I have both greps in my system because I am on 64bit and I had issues with Cygwin utilities.
In any case I have export ed $INCLUDES in my .bashrc so when I echo in Cygwin shell $ echo $INCLUDES /cygdrive/c/MinGW/include When I echo in Vim "c:\\MinGW\\include" I am using Windows version of Gvim I feel like Vim is not expanding $INCLUDES to grep in this command because if I just put straight absolute path to MinGW\include grep works works ":grep -i rand c:\MinGW\include/*" does not work ":grep -i random $INCLUDES/*" -- You received this message from the "vim_use" maillist.
