I think we can have our cake and eat it to. The problem is just that 
we are using a non-standard <sys/types.h> header file for standards 
compliance.

If you read the O'Reilly publication to the end you will find, "The 
new C99 standard has made a number of minor improvements to the C 
programming language. Among these, the most important for embedded 
programmers to understand are the contents of the new stdint.h header 
file."

The <stdint.h> header file is where the uint32_t needs to be defined 
according to the standard. On many platforms <stdint.h> will just 
include the same OS specific types in <sys/types.h>, but this is not 
required. What is required to be C99 compliant is that <stdint.h> 
defines these types. Are there any supported platforms where 
<stdint.h> does not work?
