Line 939 in version 1.11.7 of file utlib.c is the following:

        if ((cp = strchr(linebuf, '#')) != NULL)

Apparently, the compiler thinks that the strchr(...) function returns an
integer.  That function should be correctly declared to return a pointer
to a char in either ../port/misc/string.h or in the compiler's
<string.h>.  See if it is so declared.

> "utlib.c", line 958: error: invalid type combination of `int' and `int': 
> operator `[]'

Line 958 is

            strncpy(name, cp, n)[n]     = 0;

Again, the compiler apparently doesn't have a valid declaration for the
strncpy(...) function.  Check the same two header files.
