The configure script sets LLVM_ON_UNIX, not LLVM_ON_WIN32, for Cygwin:

  case $host in
  ...
  *-*-cygwin*)
    llvm_cv_link_all_option="-Wl,--whole-archive"
    llvm_cv_no_link_all_option="-Wl,--no-whole-archive"
    llvm_cv_os_type="Cygwin"
    llvm_cv_platform_type="Unix" ;;


case $llvm_cv_platform_type in
  Unix)

cat >>confdefs.h <<\_ACEOF
#define LLVM_ON_UNIX 1
_ACEOF

    LLVM_ON_UNIX=1

    LLVM_ON_WIN32=0

    ;;
