branch-1.6 distcheck failure: printf %* and integer type

[Ralf Wildenhues]

Hi Eric,

I need the following patch to get branch-1.6 M4 to pass distcheck on
GNU/Linux.

cc1: warnings being treated as errors
../../src/builtin.c: In function 'm4_maketemp':
../../src/builtin.c:1674: warning: field precision should have type 'int', but 
argument 3 has type 'size_t' [-Wformat]
[...]
../../src/macro.c:750: warning: format '%d' expects type 'int', but argument 4 
has type 'size_t' [-Wformat]

Cheers,
Ralf

        Fix -Wformat warnings.
        * src/builtin.c (m4_maketemp): Cast printf %*d length argument
        to int.
        * src/macro.c (adjust_refcount): Cast size_t to unsigned long,
        adjust printf format string.
