Hello,

 could folks who have access to non-Linux systems please try to compile the 
attached testapp and send me the output, together with the platform 
(preferably specified as what configure reports, i.e. I already have it for
checking build system type... i686-pc-linux-gnu
checking host system type... i686-pc-linux-gnu
checking target system type... i686-pc-linux-gnu ).

 Some platforms will maybe need stdlib.h instead of malloc.h, so just change 
the #if 1 to 0 (and on some it won't compile at all - I'm not interested in 
those).

 Please send the replies directly to me. Thanks.
