* Move #endif to make sure VA_COPY, LDOUBLE, etc are defined even
* if the C library has some snprintf functions already.
*
- * Darren Tucker (dtucker@zip.com.au)
+ * Darren Tucker (dtucker@zip.com.au) 2005
* Fix bug allowing read overruns of the source string with "%.*s"
* Usually harmless unless the read runs outside the process' allocation
* (eg if your malloc does guard pages) in which case it will segfault.
* From OpenSSH. Also added test for same.
+ *
+ * Simo Sorce (idra@samba.org) Jan 2006
+ *
+ * Add support for position independent parameters
+ * fix fmtstr now it conforms to sprintf wrt min.max
