[PATCH] configure: Add `AM_PROG_CC_C_O` macro This macro checks that the C compiler supports the -c and -o options together, which is needed to build the testing exe.
This macro is needed only for automake <1.14, but add it for compatibility with older environments.
[PATCH] gui: appdata: Use new format and location Lintian reports that our appdata uses legacy format and location. It refers to: https://www.freedesktop.org/software/appstream/docs/ chap-Metadata.html#sect-Metadata-GenericComponent
So adapt to the new "<id/>" element, rename "<updatecontact/>" to "<update_contact/>", and use the "<component/>" element instead of "<application/>". Also add the required "<image/>" element. Install to /usr/share/metainfo/ instead of /usr/share/appdata/.
Fixes #295
[sparschauer: Merge with "0cc3830 gui: Update screenshot ..."]
[PATCH] gui: Rename *.desktop.in and *.appdata.xml.in In order to use the new id "org.scanmem.gameconqueror", both files have to have that prefix. To show that we use the new format, rename "appdata" to "metainfo". Update translations and .gitignore as well.
