*
* ExpApplicationType --
*
* Search for the specified program and identify if it refers to a DOS,
* Windows 3.X, or Win32 program. Used to determine how to invoke
* a program, or if it can even be invoked.
*
* It is possible to almost positively identify DOS and Windows
* applications that contain the appropriate magic numbers. However,
* DOS .com files do not seem to contain a magic number; if the program
* name ends with .com and could not be identified as a Windows .com
* file, it will be assumed to be a DOS application, even if it was
* just random data. If the program name does not end with .com, no
* such assumption is made.
*
* The Win32 procedure GetBinaryType incorrectly identifies any
* junk file that ends with .exe as a dos executable and some
* executables that don't end with .exe as not executable. Plus it
* doesn't exist under win95, so I won't feel bad about reimplementing
* functionality.
*
* Results:
* The return value is one of EXP_APPL_DOS, EXP_APPL_WIN3X, or EXP_APPL_WIN32
* if the filename referred to the corresponding application type.
* If the file name could not be found or did not refer to any known
* application type, EXP_APPL_NONE is returned and the caller can use
* GetLastError() to find out what went wrong.
*
* Side effects:
* None.

* Unless WNOHANG is set and the wait times out, the process
* information record will be deleted and the process handle
* will be closed.

* to run properly under only Windows NT right now, and runs with

*
* The complete Windows search path is searched to find the specified
* executable. If an executable by the given name is not found,
* automatically tries appending ".com", ".exe", ".bat", and ".cmd" to
* the executable name.

* 0 on success, an error value otherwise.
