204 * defined and declared explicitely with globaldef and globalref.
205 * Definitions of OPENSSL_EXPORT and OPENSSL_IMPORT, to define and declare
206 * DLL exports and imports for compilers under Win32. These are a little
207 * more complicated to use. Basically, for any library that exports some
208 * global variables, the following code must be present in the header file

218 * value OPENSSL_IMPORT.
