!include directives must be followed by a space now so we don't false-match

White-space fix-ups in header file.

Win32 now (and it only runs main() from WinMain()).  This shouldn't be
necessary for MSVC builds.

It's not unlikely that any utilities using SDL will have new issues... you
may want to hold off on updates for a bit until this settles unless you
don't use SDL mode.

nanosleep was interrupted by a signal and the SLEEP parameter is > 1.
Previously, any signal wuold abort SLEEP() prematurely. A SLEEP(1) (yield)
behaves the same as before since 1 is a special value where a short-sleep
duration is fine/expected on occasion.

these are printf-style functions for inserting or appending a string into a

Eliminate duplicate case statements added in previous commit (some of these were already mapped using numeric constants).

Added more "black square" -> CP437 0xFE mappings.
Added Unicode FULL/HALF block -> CP437 mappings.

This variation on fcntl() record-locks resolves multiple-thread / forking
issue with region locks. No longer falls back to using flock() (whole-file
locks), when OFD locks are available and used successfully. At the least,
this should provide a performance boost for shared files using region
locks (on Linux). No change for Windows (region locks already worked sanely
among multiple threads) and other *nixes (that use POSIX fcntl() locks
only).
