textutils-2.0.21: SGI compiler warnings

[Nelson H. F. Beebe]

The SGI C and C++ compilers are very picky about many things, and
generally, their warnings are quite helpful in keeping code clean and
strictly Standard-conforming.

Here are the diagnostics produced for textutils-2.0.21:

cc-1177 c89: WARNING File = getdate.y, Line = 969
  The indicated argument is incompatible with the corresponding formal 
parameter.
