Hi,
I was building popt-1.13 for windows, it does not work out of the box,
but fixes are straightforward except the following one:
diff --git a/src/poptint.c b/src/poptint.c
index e99d28b..1b5fd9f 100644
--- a/src/poptint.c
+++ b/src/poptint.c
@@ -102,7 +102,11 @@ strdup_vprintf (const char *format, va_list ap)
va_copy(apc, ap); /* XXX linux amd64/ppc needs a copy. */
/*@=noeffectuncon =unrecog @*/
+#ifdef _WIN32
+ buffer = calloc(sizeof(*buffer), _vscprintf (format, ap) + 1);
+#elif // !_WIN32
buffer = calloc(sizeof(*buffer), vsnprintf (&c, 1, format, ap) + 1);
+#endif // _WIN32
vsnprintf has non-standard behaviour on windows (does not return the
required size), details [1].
I understand that windows is not a supported platform for popt (though
found some previous porting efforts [2]), so sharing just for the record.
