Thanks for reporting.
lcms uses the C feature of implicit sign conversion, so if you activate
-Wsign-conversion you will get some warnings.
This not set in the included build system.

Hello,
Just wanted to report a few warnings I am getting when building with
clang.
http://my.cdash.org/viewBuildError.php?type=1&buildid=1257347
For example:
<a
href='https://github.com/GrokImageCompression/grok/blob/master/grok/thirdparty/liblcms2/src/cmsgamma.c#L143'>grok/thirdparty/liblcms2/src/cmsgamma.c:143</a>:32:
warning: implicit conversion changes signedness: 'cmsUInt32Number' (aka 'unsigned int') to
'int' [-Wsign-conversion]
fl ->nFunctions = Plugin ->nFunctions;
~ ~~~~~~~~~^~~~~~~~~~
<a
href='https://github.com/GrokImageCompression/grok/blob/master/grok/thirdparty/liblcms2/src/cmsgamma.c#L150'>grok/thirdparty/liblcms2/src/cmsgamma.c:150</a>:63:
warning: implicit conversion changes signedness: 'int' to 'unsigned long'
[-Wsign-conversion]
memmove(fl->FunctionTypes, Plugin ->FunctionTypes, fl->nFunctions *
sizeof(cmsUInt32Number));
Thanks,
Aaron
