I just read that the naming convention is different on Windows than Linux. So we have:
libmpir.a (Unix convention) mpir.dll (Windows convention) mpir.lib (Windows convention) I do not know what needs to be passed to the mex command. However, on MinGW -lmpir should find any of the above, but it won't find a file named libmpir.lib. Perhaps this is also important on Windows. Bill.
