Preprocessor...

Hello,

In order to define the buffer-size, I would like to check the
libssh2-version.

What I did (simplifed):

#if LIBSSH2_VERSION_MAJOR == 1 && LIBSSH2_VERSION_MINOR <= 2 &&
LIBSSH2_VERSION_PATCH <= 2
#define LIBSSH2_BUFFERSIZE 1024
#endif

The problem, libssh 1.2:
#define LIBSSH2_VERSION_MAJOR 1
#define LIBSSH2_VERSION_MINOR 2
#define LIBSSH2_VERSION_PATCH

Of course, GCC reports:
ssh.cpp:30:89: error: operator '&&' has no right operand

Is there a chance to check, if LIBSSH2_VERSION_PATCH is empty?

Thanks
Marcus
