]> Has anyone managed to compile 3.11 on Vista 64 under cygwin using gcc4 [and without flexlink]? Compilation of byterun/interp.c fails miserably, with most _caml_ symbols returning 'undefined reference's. Strangely, configure thinks that my system is 32 bits, which is quite possibly another source of problems. Jacques PS: I'll soon enough install some flavour of Ubuntu on this machine too, which should fix my problems. But in the meantime, I would still like to be able to keep on working!
