When manually compiling FreeFileSync, you should also fix the following bugs in its library dependencies.
FreeFileSync generally uses the latest library versions and works with upstream to get the bugs fixed
that affect FreeFileSync. Therefore it is NOT RECOMMENDED TO COMPILE AGAINST OLDER library versions than
the ones mentioned below. The remaining issues that are yet to be fixed are listed in the following:
