    dnl This is not easily tested here; for POSIX-based systems, if executing

****************************************************************************
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 http://dev-www.libreoffice.org/bin/cygwin/make-85047eb-msvc.exe
 cp make-85047eb-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, click "All Programs", click "Visual Studio 2013", click "Visual Studio Tools", double-click "VS2013 x86 Native Tools Command Prompt" or "VS2013 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 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.

To build, issue:
$GNUMAKE

For details, run:
$GNUMAKE help

if test $_os != WINNT -a "$CROSS_COMPILING" != TRUE; then

After the build has finished, you can immediately run it using:
