Browse Source 
posixSocket.cpp:67:7: warning: ‘char*
{anonymous}::vmime_strerror_r_result(int, char*)’ defined but not
used [-Wunused-function]
   67 | char* vmime_strerror_r_result(int /* res */, char* buf) {

It is to be expected that one of the two r_result functions is going unused,
depending on whichever platform we are currently building on.
