Openssl fails to build with mingw: "does not give a valid preprocessing token"

I'm trying to build openssl 1.0.1x with a wide variety of mingw flavors and I get the following error.

In file included from \android\external\openssl\crypto\er

Do you have an idea what's wrong?

According to this, mingw headers redefines openssl symbols.

You need to undefine them.

Add the following to openssl/include/openssl/ocsp.h 

#if defined(OPENSSL_SYS_WINDOWS)
#include <windows.h>
#undef X509_NAME
#undef X509_EXTENSIONS
#undef X509_CERT_PAIR
#undef PKCS7_ISSUER_AND_SERIAL
#undef OCSP_REQUEST
#undef OCSP_RESPONSE
#endif
