is off, it doesn't do any good to ask for generation of warnings or errors.
Also libmng will generate either an error or a warning, not both,

*************************************************************************
!!!!!!!! THIS NEXT BIT IS IMPORTANT !!!!!!!!!
*************************************************************************
If you have defined MNG_FULL_CMS (and are using lcms), you will have to
think hard about the following routines.
lcms requires 2 profiles to work off the differences in the input-image
and the output-device. The ICC profile for the input-image will be
embedded within it to reflect its color-characteristics, but the output
profile depends on the output-device, which is something only *YOU* know
about. sRGB (standard RGB) is common for x86 compatible environments
(eg. Windows, Linux and some others)
If you are compiling for a sRGB compliant system you probably won't have
to do anything special. (unless you want to of course)
If you are compiling for a non-sRGB compliant system
(eg. SGI, Mac, Next, others...)
you *MUST* define a proper ICC profile for the generic output-device
associated with that platform.
In either event, you may also want to offer an option to your users to
set the profile manually, or, if you know how, set it from a
system-defined default.
TO RECAP: for sRGB systems (Windows, Linux) no action required!
for non-sRGB systems (SGI, Mac, Next) ACTION REQUIRED!
Please visit http://www.srgb.com, http://www.color.org and
http://www.littlecms.com for more info.
