[openssl-users] The less than perfect way to compile a debug library

[Dennis Clarke]

This is based on the sickly things that happen on Solaris as documented 
by various people at :

https://github.com/openssl/openssl/issues/6912

One must do :

int main(int argc, char *argv[])
{
     /* There are explicitly no run time checks for this one */
     return EXIT_SUCCESS;
}

That is horrific but allows a strict C99 compile to proceed.
