c: don't assume that UCHAR_MAX, etc. are defined

Browse Source 
A number of portability issues with GCC 4.6 .. 4.9 (inclusive):

    input.c:184:7: error: "UCHAR_MAX" is not defined [-Werror=undef]
     #elif UCHAR_MAX <= INT_MAX
           ^
    input.c:184:20: error: "INT_MAX" is not defined [-Werror=undef]
     #elif UCHAR_MAX <= INT_MAX
                        ^
    input.c:202:7: error: "USHRT_MAX" is not defined [-Werror=undef]
     #elif USHRT_MAX <= INT_MAX
           ^
    input.c:202:20: error: "INT_MAX" is not defined [-Werror=undef]
     #elif USHRT_MAX <= INT_MAX
                        ^

* data/skeletons/c.m4 (b4_c99_int_type_define): Don't assume they are
defined.
