Porting to mingw32

[Cesar Rabak]

Due to reasons I mention in another post, I started a project to port 
the GNU Prolog to an alternative to the Visual Studio compiled version 
for Windows 32.

Until now I managed to port the 1.2.16 version of GNU Prolog¹ to the 
Mingw environment and now am testing it.

The examples in ExamplesPl and ExampleFD compile and run, so at least 
the compiler seems to be in good shape!

Now, if I attempt to build the examples in the ExamplesC directory, I 
get examp working as expected (meaning: the way I understand it works 
;-), but not the new_main² program:

D:\Programacao\Prolog\GNU\gprolog-1.2.16\ExamplesC>new_main.exe

Enter a name (or 'end' to finish): peter

Fatal Error: Pl_Query_End(PL_RECOVER) but unrecoverable query

Before I start to peruse all the code behind the libbips_pl.a, is there 
something obvious I may have overlooked?

TIA

mingw being buffered.
