<p>im attempting to build on a windows 10 machine</p>
<p>i have tried msys2 mgwin32 and 64 bit</p>
<p>nothing seems to work i get errors in all stages: autogen, configure and make</p>
<p>im using mgwin64bit now and got to the make stage succesfully...</p>
<p>i am able to autogen, configure but when it comes to make i get an error:</p>
