:In cases, -Wall is bogus anyway. Here's one:
:foo.c:89: warning: char format, void arg (arg 2)
:        void *region;
:                printf("mem open failed: %s\n", region);
:
:According to standards, a void pointer may be freely used instead of any
:other type of pointer, both as an lvalue and to assign to the other pointer.
:Printf(), hence, wouldn't see a difference (of course). Gcc should not
:complain about various void pointer things like this.

    I think that's an appropriate warning... if you want to treat 'region'
    as a char *, you have to cast it to one.  The standards do not cover
    GCC's automatic var-args checking for printf() and related routines
    anyway.  I consider them 'weird' cases myself... not really standard,
    but helpful.
