 My apologies: when I wrote '-Wconst-qual' I should have written '-Wcast-qual'.  Please let me try again:

 int *f(const int *p) { return (int*)p; } /* (errror) cast discards `const' from pointer target type */

 The proper command line is:
	  gcc -c -Wcast-qual -pedantic-errors bug.c

 I believe that the error should only be a warning even with '-pedantic-errors'.

 gcc -v produces:
 Reading specs from /eda/tools/gnu/tools/gcc-2.95.2/sunos5.7/lib/gcc-lib/sparc-sun-solaris2.7/2.95.2/specs
 gcc version 2.95.2 19991024 (release)

 Thanks.
