I'm not in favour of this. Suppose I don't want to use sysutils.

* For inttostr, floattostr I can use val, and str for strtoint, 
  strtofloat.
* strpas, strpcopy and friends I can find in the strings unit
* ansi* in your unit use plain ASCII, so I can just as well use < and > 
  operators
* uppercase/lowercase I can find in the system unit as well. I can use 
  your ones for extended ASCII, but only if I manually initialize the 
  table and single byte character sets only.
* Comparemem, Comparestr has equivalents in the system unit as well.

Basically, 2/3 of this unit is duplicated functionality. Interresting 
functions I cannot get somewhere else are string and path manipulation 
routines like extractfile*, trim*, wraptext.

It would make much more sense to put this functionality in a new unit, then 
make the sysutils ones wrappers over it.
