Description of problem:

I just tried to compile package gimp-1_2_3-20_2 from Fedora.

The compiler said

1.

paint_funcs.c:992: warning: operation on `tmp' may be undefined
paint_funcs.c:992: warning: operation on `tmp' may be undefined

The source code is

          dest[b] = INT_MULT(src1[b], src1[b] + INT_MULT(2 * src2[b],
                                                         255 - src1
[b],
                                                         tmp), tmp);
You might be better off with code

	const int tmp2 = INT_MULT(2 * src2[b], 255 - src1[b],tmp);

	dest[b] = INT_MULT(src1[b], src1[b] + tmp2, tmp);

2.

The compiler also said

Lib.c(2893): remark #592: variable "RETVAL" is used before its value 
is set

The source code is

        SV *    RETVAL;
#line 2186 "Lib.xs"
        need_pdl ();
        croak (__("gimp_tile_get_data is not yet implemented\n"));
        gimp_tile_ref (tile);
        gimp_tile_unref (tile, 0);
#line 2893 "Lib.c"
        ST(0) = RETVAL;

I agree with the compiler. RETVAL needs to be initialised before use.

3.

The compiler said

gap_filter_codegen.c(229): warning #192: unrecognized character 
escape sequence

The source code is

       fprintf(l_fp, "      fprintf(stderr, \"ERROR: p_\%s_iter_ALT  
stored Data missmatch in size %%d != %%d\\n\",   \n", 
l_clean_proc_name);

%%d isn't a valid specifier. Maybe you mean %d or %%%d ?

4.

The compiler said

gap_filter_codegen.c(590): warning #192: unrecognized character 
escape sequence

Same problem as #3.
