--------------------------------------+-----------------------
 I believe that in the Tor Browser Bundle on Windows, for the tor.exe
 component, libgmpxx-4.dll is built using MinGW with exception handling
 enabled. (Omits -fno-exceptions).  MinGW has an archaic exception handling
 mechanism on Windows, using setjmp/longjmp based exceptions and
 necessitates the extra dll libgcc_s_sjlj-1.dll.

 If libgmp was build without exception handling (it appears to only use it
 3 or 4 places in the dll), it'd be possible to eliminate
 libgcc_s_sjlj-1.dll entirely.
