Long overdue MinGW port maintenance.

* Makefile: Use new EXE variable from config.mk.

* configure (exe, have_windows_h): New variables.
Handle situations with .exe suffix; on MiGW, the rm command
doesn't work on executables if the .exe suffix is not given.
New tests for localtime_r and gmtime_r.

* lib.c: Supply declarations which are missing on MinGW because
we use gcc -ansi, because MinGW doesn't follow established conventions
like -D_POSIX_SOURCE.  Supply definitions for gmtime_r, localtime_r,
setenv and unsetenv.

* parser.l: Supply declarations which are missing on MinGW.

* signal.h (async_sig_enabled): Declare differently based on
HAVE_POSIX_SIGS.
Misspelled typedef fixed in the code for !HAVE_POSIX_SIGS
that has hitherto not been compiled.
(sig_mask): Wrap declaration in #ifdef HAVE_POSIX_SIGS because
it relies on sigset_t.

* stream.c: Supply declarations which are missing on MinGW.
Include <windows.h> if we have it.
(sleep): Define for Windows.
(statf): Handle missing st_blksize and st_blocks members in struct
stat.
(stream_init): Handle numerous missing S_* macros.

* utf8.c: Supply declarations which are missing on MinGW.
