Created attachment 59927 [details] Quick and dirty patch to solve the problem. When building inside msys some packages (libpng, cairo, gtk & other) fails with some SOH chars in the Makefile. The problem is related with an extra "\r" in the output added for pkg-config.exe on windows but unnecessary for msys/mingw.
This was also reported in bug17053 and we just removed the \r code altogether. *** This bug has been marked as a duplicate of bug 17053 ***
