+- I extended a patch from David Shaw to make libcurl _always_ provide an error
+ string in the given error buffer to address the flaw mention on 21 sep 2005.

- Applied Albert Chin's patch that makes the libcurl.pc pkgconfig file get
installed on 'make install' time.
This release includes the following bugfixes:
+ o CURLOPT_ERRORBUFFER is now always filled in on errors
o curl outputs error on bad --limit-rate units
o fixed libcurl's use of poll() on cygwin
o the GnuTLS code didn't support client certificates

Thanks! (and sorry if I forgot to mention someone)
If the library does not return an error, the buffer may not have been
touched. Do not rely on the contents in those cases.
-In a few rare cases, there is no text string associated with the error in
-libcurl and then you may not get a string in the buffer even though it returns
-an error. This is considered a bug and we appreciate your reports about these
-cases. Anyway, you can avoid problems with these cases in your program by
-making sure to clear the first byte of the error buffer before you call
-curl_easy_perform().
.IP CURLOPT_STDERR
Pass a FILE * as parameter. Tell libcurl to use this stream instead of stderr
when showing the progress meter and displaying \fICURLOPT_VERBOSE\fP data.
if(newurl)
free(newurl);
+ if(res && !data->state.errorbuf) {
+ /*
+ * As an extra precaution: if no error string has been set and there was
+ * an error, use the strerror() string or if things are so bad that not
+ * even that is good, set a bad string that mentions the error code.
+ */
+ char *str = curl_easy_strerror(res);
+ if(!str)
+ failf(data, "unspecified error %d", (int)res);
+ else
+ failf(data, "%s", str);
+ }

/* run post-transfer uncondionally, but don't clobber the return code if
we already have an error code recorder */
res2 = Curl_posttransfer(data);
