VC++ support patch

[Boehne, Robert]

Hello,

Current CVS libltdl almost compiles in Visual C++ 6, the problem is with the 
macro LT_USE_WINDOWS_DIRENT_EMULATION.  It is #defined like so:
<SNIP>
#else  /* __WINDOWS__ */
/* Use some wrapper code to emulate dirent on windows..  */
# define LT_USE_WINDOWS_DIRENT_EMULATION
#endif
<SNIP>

But the test for it is "# if LT_USE_WINDOWS_DIRENT_EMULATION" which throws an 
'invalid integer expression' error.  There are two ways to make it work, in the 
line where it is defined, #define it to "1", or change the value check to a 
check for definition.

Thanks,

Robert
