Problem: C89 requires signal handlers to return void. Solution: Drop RETSIGTYPE and hard-code a void return value.

/* 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
