Subject: [PATCH] build: Fix 'incompatible pointer types' warning on i686

This fixes a recent Fedora build, which failed on i686 architecture
with "incompatible pointer types" error:

libpst.c: In function 'pst_read_block_size':
libpst.c:3832:36: error: passing argument 2 of 'uncompress' from incompatible pointer type [-Wincompatible-pointer-types]
 3832 |     if (uncompress((Bytef *) *buf, &result_size, (Bytef *) zbuf, size) != Z_OK || result_size != inflated_size) {

      |                                    |
      |                                    size_t * {aka unsigned int *}
In file included from libpst.c:9:
