Hi Guys,
Please could I have permission to apply the patch below ? Ideally for
both mainline and the 4.9 branch.
The patch adds a file called "default-manifest.o" to the end of a
final link command line for the Cygwin and MinGW targets. The file is
only added if it can be found in the library search path(s), so the
patch will have no effect if the file does not exist.
The default manifest file contains a resource section (.rsrc) holding
information necessary for the binary to be run under Windows 8. It is
placed last on the linker command line so that a user provided
manifest, if there is one, will take precedence over the default
manifest.
The manifest used to be automatically added by the linker, but this
proved to be problematic as the linker is not good at selectively
inserting binaries. The manifest itself is provided by a separate
project which will have to become a new dependency for the Cygwin and
MinGW projects.
Cheers
Nick
