Bug 53128

Same problem here while cross-compiling cairo-1.12.16.

I am on a Linux 32 bit operating system (Slackware 14.1) and I have a cross-compiler based on:
- binutils-2.24.51
- gcc-4.9.1
- mingwrt-3.20.2
- w32api-3.17.2

Here is how to reproduce:
$ PKG_CONFIG_PATH="/usr/i686-pc-mingw32/lib/pkgconfig"
$ ./configure --prefix=/usr/i686-pc-mingw32 --host=i686-pc-mingw32 --disable-lto --disable-gtk-doc --disable-test-surfaces --disable-gcov --disable-xlib --disable-xlib-xrender --disable-xcb --disable-quartz --disable-quartz-font --disable-quartz-image --disable-os2 --disable-beos --disable-directfb --disable-atomic --enable-win32 --enable-win32-font --enable-png --enable-ft --enable-ps --enable-pdf --enable-svg --disable-pthread
$ make
[...]

make[1]: *** [all-recursive] Error 1
make[1]: Leaving directory `/tmp/build/cairo-1.12.16'

Any idea to solve this problem?

Cross compiling works fine with mingw-64. The script at http://rodrigo.dualnot.com/en/mingw-cross-compiler/ works perfectly on Ubuntu 14.04.
