+Subject: [PATCH] setup.py: move swig default includes before openssl
+
+Move swig default includes before openssl to avoid the following build
+failure when cross-compiling for some architectures (e.g. arm, mips):
+
+swig -python -py3 -D__x86_64__ \
+ -I/srv/storage/autobuild/run/instance-0/output-1/host/mipsel-buildroot-linux-gnu/sysroot/usr/include/python3.9 \
+ -I/srv/storage/autobuild/run/instance-0/output-1/host/mipsel-buildroot-linux-gnu/sysroot/usr/include \
+ -I/srv/storage/autobuild/run/instance-0/output-1/host/mipsel-buildroot-linux-gnu/sysroot/usr/include/openssl \
+ -I/srv/storage/autobuild/run/instance-0/output-1/host/opt/ext-toolchain/bin/../lib/gcc/mipsel-buildroot-linux-gnu/8.3.0/include \
+ -I/srv/storage/autobuild/run/instance-0/output-1/host/opt/ext-toolchain/bin/../lib/gcc/mipsel-buildroot-linux-gnu/8.3.0/include-fixed \
+ -I/srv/storage/autobuild/run/instance-0/output-1/host/opt/ext-toolchain/bin/../lib/gcc/mipsel-buildroot-linux-gnu/8.3.0/../../../../mipsel-buildroot-linux-gnu/include \
+ -I/srv/storage/autobuild/run/instance-0/output-1/host/mipsel-buildroot-linux-gnu/sysroot/usr/include \
+ -includeall -modern -builtin -outdir \
+ /srv/storage/autobuild/run/instance-0/output-1/build/python-m2crypto-0.36.0/M2Crypto -o SWIG/_m2crypto_wrap.c SWIG/_m2crypto.i
+Deprecated command line option: -modern. This option is now always on.
+/srv/storage/autobuild/run/instance-0/output-1/host/mipsel-buildroot-linux-gnu/sysroot/usr/include/bits/types.h:139:
+Error: CPP #error "". Use the -cpperraswarn option to continue swig processing.
+
+This build failure is probably raised because swig includes a wrong types.h file
+from the openssl directory (e.g.
+/srv/storage/autobuild/run/instance-0/output-1/host/mipsel-buildroot-linux-gnu/sysroot/usr/include)
+
