[gdal-dev] libcurl and the certificates and Windows

For quite some time I cannot use the 'vsis' because of certificates issue.
For example, a GMT test that has a command like this no longer works on
ERROR 11: HTTP response code: 301 - SSL certificate problem: unable to get
local issuer certificate
gdalinfo failed - unable to open
It used to work but probably with an older libcurl dll.
The above is with my own build gdal and dependencies (libcurl included)
but the same happens with the gisinternals binaries.
I have re(and re)ad this page about the certificates
but regarding Windows and the curl-ca-bundle.crt file what is said about
it simply does not work. The only thing that works is setting the ENV
Now, we had this in GMT recently and I used the nuke option
curl_easy_setopt (Curl, CURLOPT_SSL_VERIFYPEER, 0L); /* Tell libcurl to
not verify the peer */
so tried to do the same thing in the GDAL code (the obvious point seamed
to be VSICurlSetOptions in cpl_vsi_curl.cpp) but still does not work.
OSGeo4W works but probably because they are still using a 4 years old
Am I the only one seeing this?
