…cc-14)

Upcoming `gcc-14` enabled a few warnings into errors, like
`-Wint-conversion`. This caused `afdko` build to fail as:

    /build/afdko/c/shared/source/uforead/uforead.c:1243:20: error: passing argument 2 of ‘message’ makes pointer from integer without a cast [-Wint-conversion]
     1243 |         message(h, ufoErrParse, "Encountered glyph reference %s in alternate layer's contents.plist with an empty file path. ", glyphName);
          |                    ^~~~~~~~~~~
          |                    |
          |                    int

It looks like `ufoErrParse` is an unexpected parameter here.

While at it fixed build failure related to int/pointer error:

    /build/afdko/c/shared/source/uforead/uforead.c:2007:16: error: returning ‘void *’ from a function with return type ‘long int’ makes integer from pointer without a cast [-Wint-conversion]
     2007 |         return NULL;
          |                ^~~~

…e (gcc-14)

Upcoming `gcc-14` enabled a few warnings into errors, like
`-Wincompatible-pointer-types`. This caused `afdko` build to fail as:

    /build/afdko/c/shared/source/tx_shared/tx_shared.c: In function ‘stmInit’:
    /build/afdko/c/shared/source/tx_shared/tx_shared.c:526:20: error: assignment to ‘size_t (*)(ctlStreamCallbacks *, void *, char **)’ {aka ‘long unsigned int (*)(struct ctlStreamCallbacks_ *, void *, char **)’} from incompatible pointer type ‘size_t (*)(ctlStreamCallbacks *, Stream *, char **)’ {aka ‘long unsigned int (*)(struct ctlStreamCallbacks_ *, Stream *, char **)’} [-Wincompatible-pointer-types]
      526 |     h->cb.stm.read = stm_read;
          |                    ^

The change fixes opaque parameter to pass as `void *`.

…rence (gcc-14)

Upcoming `gcc-14` enabled a few warnings into errors, like
`-Wincompatible-pointer-types`. This caused `afdko` build to fail as:

    /build/afdko/c/shared/source/t1write/t1write.c: In function ‘saveCstr’:
    /build/afdko/c/shared/source/t1write/t1write.c:348:28: error: passing argument 3 of ‘writeTmp’ from incompatible pointer type [-Wincompatible-pointer-types]
      348 |         if (writeTmp(h, 1, &info->iFD))
          |                            ^~~~~~~~~~
          |                            |
          |                            uint16_t * {aka short unsigned int *}

The code attempts to use only one byte of 16-bit value. The code very
likely is broken on a big-endian system.

The change explicitly truncates 16-bit value down to 8 bit value to
retain existing behaviour on both BE and LE systems.
