gcc-4.8.3-1 is now uploaded for both 32-bit and 64-bit Cygwin. This
includes a patch to automatically link in the default manifest for
executable files.
Known issues:
Cygwin 64-bit gcc-4.8.3-1 debuginfo package is missing and was not
generated by cygport, I am still investigating this.
I've made a new version of binutils available for installation. This is
a refresh against the official git repository. The binutils package
contains the GNU assembler, linker and binary utilities. It is
available in the Devel category under Cygwin's setup.
