# This is massive hack to work around an incompatibility with the system Qt5
# libraries. On 0.93.1, the dynamic linker fails to start XnView, complaining
# that:
# symbol _ZNSt20bad_array_new_lengthD1Ev version Qt_5 not defined in file libQt5Gui.so.5 with link time reference
# (and other functions related to the std::bad_array_new_length class).
#
# It seems that the Qt5 libraries shipped in the archive changed in 0.93.1,
# and they now declare these functions, but our system libs on Arch don't!
# Since these are STL functions, the workaround is to manually define these
# functions in a tiny shared library, and implement them by calling the STL
# functions in libstdc++. This is frankly horrible, but it has worked fine
# since 0.93.1 so fingers crossed it will stay this way!
