Compiletime error on OpenIndiana (OpenSolaris/SunOS5+/illumos)

[habaneropep2019]

Same code compiles correctly on gnu-linux-g++ target, so maybe there is a mixup of GNU/gcc and Solaris libraries happening somewhere?

Configured with ./configure -sm -shared -debug -qt-zlib -system-jpeg -qt-libpng

Currently compiling with threads support doesn't work either.
