The message above shows 'PTR.C'. If the filename happens to be seen as 
having an uppercase 'C', gcc will assume your file is C++ but will link 
in only C libraries running in this trouble.

Try to rename the file so it appears to gcc as C. If this is not 
acceptable to you, for checking if is this behaviour the reason, invoke 
gcc as follows:

gcc -x c ptr.c

and report the results.
