As noted at:

progopt library fails to link on mingw as dll. After some searching
around, I found out that using -Wl,--enable-runtime-pseudo-reloc flag
during linking, it works properly.

However, one should be warned that this flag should not be used when
some of the code isn't compiled with the same compiler (e.g. mixing
dlls/binaries from different compilers) - the resulting binary will
always crash.
