CURLOPT_STDERR.3: does not work with libcurl as a win32 DLL

Browse Source 
This is the exact same limitation already documented for
CURLOPT_WRITEDATA but should be clarified here. It also has a different
work-around.

Pass a FILE * as parameter. Tell libcurl to use this \fIstream\fP instead of
stderr when showing the progress meter and displaying \fICURLOPT_VERBOSE(3)\fP
data.
If you are using libcurl as a win32 DLL, this option will cause an exception
and crash in the library since it cannot access a FILE * passed on from the
application. A work-around is to instead use \fICURLOPT_DEBUGFUNCTION(3)\fP.
