dnl configure.ac serves as input for the GNU autoconf package

# The version number in the second argument to AC_INIT should be four numbers separated by
# periods. Some parts of the code requires the first one to be less than 128 and the others to be less
# than 256. The four numbers can optionally be followed by a period and a free-form string containing
# no spaces or periods, like "frobozz-mumble-42" or "alpha0". If the free-form string ends with one or
# several non-alphanumeric characters, those are split off and used only for the
# ABOUTBOXPRODUCTVERSIONSUFFIX in openoffice.lst. Why that is necessary, no idea.

or get and install one from http://www.nasm.us/

****************************************************************************
WARNING:
Your make version is known to be horribly slow, and hard to debug
problems with. To get a reasonably functional make please do:

to install a pre-compiled binary make for Win32

 mkdir -p /opt/lo/bin
 cd /opt/lo/bin
 wget https://dev-www.libreoffice.org/bin/cygwin/make-4.2.1-msvc.exe
 cp make-4.2.1-msvc.exe make
 chmod +x make

to install from source:
place yourself in a working directory of you choice.

 git clone git://git.savannah.gnu.org/make.git

 [go to Start menu, open "Visual Studio 2017", click "VS2017 x86 Native Tools Command Prompt" or "VS2017 x64 Native Tools Command Prompt"]
 set PATH=%PATH%;C:\Cygwin\bin
 [or Cygwin64, if that is what you have]
 cd path-to-make-repo-you-cloned-above
 build_w32.bat --without-guile

should result in a WinRel/gnumake.exe.
Copy it to the Cygwin /opt/lo/bin directory as make.exe

Then re-run autogen.sh

Note: autogen.sh will try to use /opt/lo/bin/make if the environment variable GNUMAKE is not already defined.
Alternatively, you can install the 'new' make where ever you want and make sure that `which make` finds it.
