# This fixes the same symbol being used for globals in different objects
# While linkers should be able to unravel this could lead to optimization
# issues.
# See:
"${FILESDIR}/${P}-missing-include-guards.patch"
"${FILESDIR}/${P}-sdl_scancodes.patch"
# This fixes an issue with accessing a 2D array like a 1D array
# (i.e. acessing a [256][3] array by [0][69]
# This should work in practice but leads to undefined behavior
# which in turn can lead to problems with loop optimization
# See: -Waggressive-loop-optimizations
