/* autoconf cannot fiddle out declarations. Use our homebrewn tools. (jw) */
/*
 * Declarations that may cause conflicts belong here so that osdef.sh
 * can clean out the forest. Everything else belongs in os_unix.h
 *
 * How this works:
 * - This file contains all unix prototypes that Vim might need.
 * - The shell script osdef.sh is executed at compile time to remove all the
 *   prototypes that are in an include file. This results in osdef.h.
 * - osdef.h is included in vim.h.
 *
 * sed cannot always handle so many commands, this is file 1 of 2
