14918 WARNING:
14919 Your make version is known to be horribly slow, and hard to debug
14920 problems with. To get a reasonably functional make please do:
14921
14922 to install a pre-compiled binary make for Win32
14923
14924  mkdir -p /opt/lo/bin
14925  cd /opt/lo/bin
14926  wget https://dev-www.libreoffice.org/bin/cygwin/make-4.2.1-msvc.exe
14927  cp make-4.2.1-msvc.exe make
14928  chmod +x make
14929
14930 to install from source:
14931 place yourself in a working directory of you choice.
14932
14933  git clone git://git.savannah.gnu.org/make.git
14934
14935  [go to Start menu, open "Visual Studio 2019" or "Visual Studio 2022", and then click "x86 Native Tools Command Prompt" or "x64 Native Tools Command Prompt"]
14936  set PATH=%PATH%;C:\Cygwin\bin
14937  [or Cygwin64, if that is what you have]
14938  cd path-to-make-repo-you-cloned-above
14939  build_w32.bat --without-guile
14940
14941 should result in a WinRel/gnumake.exe.
14942 Copy it to the Cygwin /opt/lo/bin directory as make.exe
14943
14944 Then re-run autogen.sh
14945
14946 Note: autogen.sh will try to use /opt/lo/bin/make if the environment variable GNUMAKE is not already defined.
14947 Alternatively, you can install the 'new' make where ever you want and make sure that `which make` finds it.
