I have compiled with Microsoft Visual C++ 6.0 including the latest service packs and SDK 2003 includes+libs.
Everything works fine but iso_speed is _always_ 0.
I have tried it with code alignment of 4, 8 and even 16 bytes. iso_speed is still 0.
(There is no possibility to use another compiler or compile libraw by myself).
Please help :-)
