Cannot compile on Arch Linux due to conflicing int types

Cannot compile on Arch Linux due to conflicing int types

[Stephen Gregoratto]

The ohash functions included in tag.c use the stdint.h types, but tag.c
does not include them directly. This leads to compile errors like so:

In file included from mandoc_ohash.h:20,
                 from tag.c:31:
compat_ohash.h:56:20: error: unknown type name ‘uint32_t’; did you mean ‘u_int32_t’?
   56 |      const char *, uint32_t);
      |                    ^~~~~~~~
      |                    u_int32_t
compat_ohash.h:58:14: error: unknown type name ‘uint32_t’; did you mean ‘u_int32_t’?
   58 |      size_t, uint32_t);
      |              ^~~~~~~~
      |              u_int32_t
compat_ohash.h:67:1: error: unknown type name ‘uint32_t’; did you mean ‘u_int32_t’?

thank you very much for the very useful report.  It really helps
to find such glitches long before i call for release testing because
it reduces the strain on everyone having to re-test on all platforms
after last-minute fixes had to be rushed in for bugs found no earlier
than during release testing itself.  So every bug found *before*
the start of release testing really improves the situation.

Indeed, you are right, <stdint.h> is required before <ohash.h>,
both the ohash_init(3) manual page and mandoc_headers(3) say so.

Fixed with the commit appended below.

Yours,
  Ingo
