I believe that flexlink is needed for all Windows ports (Cygwin included - as in README.win32) as it's used internally to simplify linking even when creating Cygwin executables. > Compilation of byterun/interp.c fails miserably, with most _caml_ > symbols returning 'undefined reference's.

When you run Cygwin's bash, you're in the WOW subsystem and will so the architecture will report itself as 32-bit (if you look in task manager then you'll see that bash.exe is starred). > > Jacques > > PS: I'll soon enough install some flavour of Ubuntu on this machine > too, > which should fix my problems.

I imagine that there's a reason that you're both building your own OCaml and also using the Cygwin port specifically but just in case: the MinGW and MSVC64 builds both definitely work on Vista64...
