Help with libwinprthread-1.dll

Hi there

I'm trying to compile Cairo for perl (strawberry 5.24) on windows 7. I have=
 download the package Cairo using msys64.

From the CPAN/Build Cairo folder I have created the makefile with

perl Makefile.pl INC=3D"-IC:/strawberry/c/include/freetype2 -IC:/msys64/min=
gw32/include/cairo -IC:/msys64/mingw32/include -I. -I./build" LIBS=3D"-Lc:/=
msys64/mingw32/lib" verbose

In the C:\msys64\mingw32\lib folder I have copied *.dll.a on *.a files to p=
revent undefined reference errors when running dmake, following someone's (=
Rob) suggestion on the mingw-users list.

dmake executes without error.

dmake test=20

fails with a msgbox "The procedure entry point pthread_setname_np could not=
 be located in the dynamic link library libwinprthread-1.dll"=20
and in the console:
t/00-loading.t ....
#   Failed test at t/00-loading.t line 15.
t/00-loading.t .... 1/18 Bareword "Cairo::LIB_VERSION" not allowed while "s=
trict subs" in use at t/00-loading.t line 18.

t/00-loading.t .... Dubious, test returned 255 (wstat 65280, 0xff00)
Failed 17/18 subtests etc...

Is it that my libwinpthread-1.dll in my c:/strawberry/perl/bin is not the c=
ompatible with the one in c:/msys64/mingw32/bin/ (there size differs 51 KB =
/ 65 KB) ?

Thanks for any help
