Yes. If you look at my output, you'll see I get the same thing. I don't
get that however if I don't have --disable-cpp on the configure. Then it
goes further and bombs making pcretest.exe. But regardless, I still
always got pcre.dll and pcreposix.dll in my .libs directory. I admit
that when I first started trying to build the libraries I was thrown by
the fact that make didn't run to completion. In fact, I was so new to
Msys/mingw and knew nothing of Unix that I didn't know what was wrong.
But once I linked pcretest by hand and ran the the RunTest.bat file
(after relocating the test data so the bat file would work) I could see
that the libraries in .libs were fine (at least after I disabled stack
for recursion, before that some of tests would crash). To finish
sucessfully with only errors on fr_FR locale, pcre needs at least 8mb of
stack on Windows when not disabling stack for recursion. At one point I
knew how to do that using configure/make, but since that left us open to
crashes in our application, I started disabling use of the stack altogether.
