Exported header files used by applications should allow the strictest compiler flags. Language extensions used in many places must be explicitly marked to avoid warnings and compilation failures. Unnamed structs/unions are allowed since C11, however many compiler versions do not use this mode by default. This commit prevents the following errors: error: ISO C99 doesn't support unnamed structs/unions error: struct has no named members Signed-off-by: Adrien Mazarguil <adrien.mazarguil@6wind.com>
