Subject: [PATCH] com32/modules/pxechn.c: use proper type in struct data_area
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Use a size_t for the size field, so that we meet the expectations of
the loadfile() function.

Fixes a build issue with GCC >= 14:

com32/modules/pxechn.c:985:38: error: passing argument 3 of ‘loadfile’ from incompatible pointer type [-Wincompatible-pointer-types]
  985 |     if (loadfile(pxe.fn, &file.data, &file.size)) {
      |                                      ^~~~~~~~~~
      |                                      |
      |                                      addr_t * {aka unsigned int *}

In file included from com32/modules/pxechn.c:33:
com32/include/syslinux/loadfile.h:11:37: note: expected ‘size_t *’ {aka ‘long unsigned int *’} but argument is of type ‘addr_t *’ {aka ‘unsigned int *’}

      |                                     ^~~~~~~~
