--- Comment #2 from Jan Henrik Sylvester me@janh.de 2008-06-01 16:58:25 --- Created an attachment (id=13567) --> (http://bugs.winehq.org/attachment.cgi?id=13567) Fix incompatibility by undef before ssl.h include
This seems not to be the first incompatibility of this kind. dlls/wininet/internet.h already has a section of undefs before the include of openssl/ssl.h to "avoid conflict with wincrypt.h". Adding X509_EXTENSIONS to that list fixes the build.
