integer-gmp/gmp/gmpbuild/configure.in has AM_PROG_LEX which requires (f)lex.
it also has AC_PROG_YACC which I'd guess requires yacc/bison.

I feel your pain. The Windows instructions could definately use some
updating. :)

I ended up getting an error during stage 2 about the iconv.dll not
being findable. (I'm guessing the new msys/mingw autosmarted GHC
boot/configure or cabal configure process somehow ....)

ghc-stage2 was trying to build vector-0.8 and failed during Loading
package base ... (due to not finding iconv.dll)

That sounds like it. I'll go back and look at that after I see how bad
the iconv issue is to chase down.
That msys install the wiki points everybody at really is ancient. :)
