+ -- When a library A needs symbols from a library B, the order in
+ -- extra_libraries/extra_ld_opts is "-lA -lB", because that's the
+ -- way ld expects it for static linking. Dynamic linking is a
+ -- different story: When A has no dependency information for B,
+ -- dlopen-ing A with RTLD_NOW (see addDLL in Linker.c) will fail
+ -- when B has not been loaded before. In a nutshell: Reverse the
+ -- order of DLLs for dynamic linking.
+ -- This fixes a problem with the HOpenGL package (see "Compiling
+ -- HOpenGL under recent versions of GHC" on the HOpenGL list).
