As written in comment 1, there are official GCC 4.5.0 binaries. I do not know how they integrate into the package manager of Cygwin, but one can at least download them from the official FTP server. I wouldn't be surprised if those will install the compiler as "gfortran-4.5". As libgfortran of GCC 4.5 is backward compatible with GCC 4.3/4.4, you could consider to just install the newer library. But you could also use the newer version of the compiler. For the new features, cf. http://gcc.gnu.org/wiki/GFortran#news
