Changeset 2962 for trunk/coin.m4

Message:

remove --enable-doscompile=mingw

-mno-cygwin does not work on current cygwin systems anymore

introduced option --enable-msvc to replace --enable-doscompile=msvc, but
the latter can still be used, too

effect of --enable-msvc is to

  • reorder compiler preference to prefer Intel/MS compiler over GNU
  • ensure that LD is set to link
  • ensure that cp is used for linking (probably happened anyway)
