Strange.  I installed Grep from a zip file, not with a self-installing
setup program, and I clearly see only pcre.dll in the
grep-2.5.1a-dep.zip archive I still have on my machine.

What is the time stamp of pcre3.dll on your system?

Also, does it help to reinstall Grep?

Yes, I've tried that, and it works as I expect: it finds text
case-insensitively no matter if I specify the search string in
uppercase or lowercase.

FWIW, I don't recommend this.  MSYS ports are meant for one purpose
only: to be able to build MinGW ports of other tools.  For that
purpose, they sometimes tweak the command-line arguments in order to
allow running those commands from Unix shell scripts.  In particular,
they convert Windows file names with drive letters into pseudo-Posix
file names that start with a forward slash.  If a command-line
argument looks like a file name, but really isn't, this conversion
could have devastating effect on the Grep command.
