I've just had the same error message after upgrading from 1.3.18 to 
1.3.19 when starting a bash shell. I closed all bash shells down before 
upgrading. The Task Manager showed no Cygwin processes running. However, 
as Chris suggests might be the case, Cygwin is being used. The problem 
is because I launched gvim (native Windows build) from the Cygwin shell 
as a background task before upgrading:
gvim file &

Only after closing these instances, could I launch a bash shell without 
the "shared version mismatch detected error". Might I suggest the error 
message is expanded to include something along the lines: "Also check 
that you have no Cygwin processes running, including background tasks 
launched from a different version of Cygwin."
