for -Wl, see the gcc man page:
,----
|  -Wl,option
|    Pass option as an option to the linker.  If option contains
|    commas, it is split into multiple options at the
|    commas.

=> for -export-dynamic see the ld man page:
,----
|  --export-dynamic
|        When  creating a dynamically linked executable, add all

|        bol table is the set of symbols which are visible from
|        dynamic objects at run time.
| 
|        If you do not use this option, the dynamic symbol table will
|        normally contain only  those  symbols  which  are
|        referenced by some dynamic object mentioned in the link.
| 
|        If  you use "dlopen" to load a dynamic object which needs to
|        refer back to the symbols defined by the program,
|        rather than some other dynamic object, then you will probably

Not sure about that one ;-)

Assuming there is a windows version of ruby you probably just can
compile without -Wl,--export-dynamic (because windows does not support
it anyway AFAIR).
Or you comile it statically using
./configure --disable-shared
(see also ./configure --help)
