Are you using C++ by any chance? Coudl be a conflict between int func() which
can be interpreted as unspecified arguments in C and no arguments in C++.
You could use a function pointer cast.
i2d_ASN1_SET_OF_<foo>() isn't the best way of doing that any more. The new
template code is preferred. Something like:
typedef STACK_OF(X509_EXTENSION) X509_EXTENSIONS;
ASN1_ITEM_TEMPLATE(X509_EXTENSIONS) =
ASN1_EX_TEMPLATE_TYPE(ASN1_TFLG_SEQUENCE_OF, 0, Extensions,
X509_EXTENSION)
ASN1_ITEM_TEMPLATE_END(X509_EXTENSIONS)
IMPLEMENT_ASN1_FUNCTIONS(X509_EXTENSIONS)
then use i2d_X509_EXTENSIONS().
Which reminds me.. we should really have a definition of X509_EXTENSIONS
in the core code.
