vsnprintf portability

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Win32 vsnprintf returns -1 upon truncation, therefore the overflow
checks of xdelta on windows are not reliable.

What version of the product are you using? On what operating system?
- svn-207/208 on linux, win32, djgpp

Please provide any additional information below.

The attached patch provides more portability, I think. Even with that,
there are still non-C99-compliant vsnprintf implementations out there..

Regards,
Ozkan

I thintk this was missed in xdelta3-main.h:

-#define VC do { if (((ret = snprintf 
+#define VC do { if (((ret = snprintf_func

Thanks,
