Do you have any idea if this means it will only build with new versions
of OpenSSL on cygwin? IE, with this patch in place on an older system
does it still build there too?
Hello Wes,
This patch should work for both newer and older Cygwin versions. The
description of commit 0657b90b7181 is as follows:
Cygwin, scapi.h: Fix build
Recent versions of the Cygwin openssl header files and <windows.h>
are incompatible because both define X509_NAME unless OPENSSL_SYS_WIN32
is defined. Hence avoid including openssl header files in source files
that include <windows.h>.
Defining WIN32_LEAN_AND_MEAN causes windows.h not to include the header
file that defines all the X509_* symbols, including X509_NAME. In other
words, the patch I posted is a better version of commit 0657b90b7181.
Bart.
