MingW32 compilation error: conflicting types for 'l_jpegSetNoChromaSampling'

[GoogleCodeExporter]

Trying to build on a mingw32 environment, I get this error:

jpegiostub.c:1:0: warning: -fPIC ignored for target (all code is position 
independent)

Same issue on a i686-pc-linux-gnu system using gcc 4.4.3

Thanks for the notification.

The signature for that function, which is incorrect
in the jpegiostub.c file, will be fixed in 1.66,
due out in a week.

Until then, you can build if you have that function return void:

void l_jpegSetNoChromaSampling(l_int32 flag)
{
    L_ERROR("function not present", "l_jpegSetNoChromaSampling");
    return;
}
