[Bug-tar] .... illegal C code.....

[Joerg Schilling]

This is a second try, the first mail did not arrive.

A void pointer points to an object of _unknown_ size, therefore
a C-compiler needs to multiply with an unknown value...

Note that this is really more than a warning. It is a _hard_ C-violation.
If Sun-cc would not not implement GCC bugs for your convenience, compilation
would abort here.


cc -DHAVE_CONFIG_H -I. -I. -I.. -I../lib -I../ -I../lib   -I/usr/local/include  
-g -c rmt.c
"rmt.c", line 288: warning: argument #2 is incompatible with prototype:
        prototype: pointer to pointer to char : "../lib/getopt.h", line 209
        argument : pointer to const pointer to char

It makes sense to write code in a way that the compiler does not give warnings
with warnings disabled (as in this case).
