inlined rdtsc() function in header file

["C. W. Wright (1698)" <wright@lidar.wff.nasa.gov>]

Greetings!,

  I've been using the inline asm function David posted to the list a few
weeks ago.  It works great and avoids the assembly function call to a
single instruction ( tsc ) I had been using before.

I can't get it to reside in a header file which is included by two source
files that compiled and linked together to produce a single executable.
I get a redefinition error from gcc.  Actually, if I paste the code into
any two files which are linked together later, an error occurs.  Anyone
have any idea how to get the __inline__ function to work in multiple
source files which result in one binary?

Best regards,
Wayne
