It warns only on ARM because on x86 integers can be accessed other than on 4-byte boundaries. This means this warning is irrelevant on x86.

I'm wondering if we shouldn't fix these casts instead of removing the warnings. A quick grep reveals that both GTK and QT use -Wcast-align:

$ find . -name '*.pri' -exec grep Wall {} \;
*-g++*:QMAKE_CXXFLAGS += -Wall -Wextra -Wreturn-type -fno-strict-aliasing -Wcast-align -Wchar-subscripts -Wformat-security -Wreturn-type -Wno-unused-parameter -Wno-sign-compare -Wno-switch -Wno-switch-enum -Wundef -Wmissing-noreturn -Winit-self

$ find . -name GNUmakefile.am -exec grep -B1 -A5 Wall {} \;
global_cppflags += \
    -Wall -W -Wcast-align -Wchar-subscripts -Wreturn-type \
    -Wformat -Wformat-security -Wno-format-y2k -Wundef \
    -Wmissing-format-attribute -Wpointer-arith -Wwrite-strings \
    -Wno-unused-parameter -Wno-parentheses \
    -fno-exceptions -DENABLE_GLIB_SUPPORT=1
