Some language bindings have issues with exported variables. The static context is currently exported as a variable:

SECP256K1_API const secp256k1_context *secp256k1_context_static;

which is implemented as:

const secp256k1_context *secp256k1_context_static = &secp256k1_context_static_;

A more portable way would be to provide it through a function:

SECP256K1_API const secp256k1_context *secp256k1_context_static(void);

with implementation:

const secp256k1_context *secp256k1_context_static(void)
{
    return &secp256k1_context_static_;
}

PS: It is clear that changing the symbol into a function is a breaking change and therefore off the table. However, please consider adding a new symbol with the proposed implementation.
