>          Components: core/transport
>    Affects Versions: 1.6.0
>         Environment: openSUSE 11.3
> turn warnings into errors

> Using configure --enable-libcurl triggers the following compile errors when warnings
are turned into errors at compile time:
> libcurl/axis2_libcurl.c: In function 'axis2_libcurl_send':
> libcurl/axis2_libcurl.c:114:19: error: 'content_type' may be used uninitialized in this
function
> libcurl/axis2_libcurl.c: In function 'axis2_libcurl_send':
> libcurl/axis2_libcurl.c:143:5: error: call to '_curl_easy_setopt_err_error_buffer' declared
with attribute warning: curl_easy_setopt expects a char buffer of CURL_ERROR_SIZE as argument
for this option
> While the first error is harmless as 'content_type' is not used in an uninitialized fashion,
the second error has the potential to trigger memory corruption if an error occurs.
