Added isdir function to check if a path is a directory.
Added BACKSLASH macro (os-specific path separator).

Added isdir function to check if a path is a directory.

Created new Make 'include file', targets.mak which lists all targets for all and adds new 'clean' rule.
Makefile.gnu now builds utilities (fixsmb, chksmb, smbutil, and baja).

Function declared as export if SMB_EXPORTS is defined, import otherwise.

Added support for separate executable and library output directory (object files are not compatible due to imported symbols).

Only exported function prototypes are now included in sbbs.h when included from external module (e.g. ftpsrvr.c).

This is apparently the only way to generated MSVC __cdecl-compatible names.
The stack maintenance isn't supposed to be compatible, but it appears to work. <shrug>
