To Reproduce

1. Have GCC >= 14
2. Try to build curl_cffi

Expected behavior No build failure.

Versions

• OS: linux x64
• curl_cffi version 0.7.4

Additional context See the GCC 14 porting guide about -Werror=incompatible-pointer-types (https://gcc.gnu.org/gcc-14/porting_to.html#incompatible-pointer-types) with GCC 14 the warnings became errors:

GCC no longer allows implicitly casting all pointer types to all other pointer types.
