ANSI-compatibility strategy:
1. If ANSIPROTO is defined, function prototypes are used, ANSI-style.
If it is not defined, regular function declarations (without a
parameter list) are used. This is achieved with the use of
the PARMS macro.
2. If STDINCLUDE is defined, ANSI-conformant header files are
included. Otherwise functions that would be declared in such
header files are declared individually.

/*
BIGBUF If defined, setvbuf() will be used to set input and
output buffers to BIGBUF characters
BINCHAR This must be a macro accepting a single character
argument and returning nonzero if and only if that
character is a binary character. By default, BINCHAR
is defined to look up a table, and the table is compiled
in by defining USE_TABLE.
CHECK_BREAK If your operating system requires programs to check
for user interrupts at intervals, define CHECK_BREAK to
be a function or macro that checks for a user interrupt.
Flip will call this at intervals. If not needed,
define CHECK_BREAK to be null.
DELFILE Must be a function or macro that will accept one filenames
and delete that file, returning zero on success, nonzero
on failure.
GETFT Must be a macro with usage GETFT(file,name,var) that will
take an open file, a filename, and a variable name, and
put in that variable the timestamp of the file.
INT_EXIT If USE_SIG is defined, INT_EXIT must be defined to
be the exit code returned by flip when its execution
is aborted by a user interrupt.
MVFILE Must be a function or macro that will take two filenames
and rename the first file to the second file, returning
zero on success, nonzero on failure.
NIX If this symbol is defined, some things common to most
implementations of **IX get defined and need not be
individually defined.
PATHSIZE size of buffer(s) to use to hold pathname(s)
PICKNAME Do "#define PICKNAME" if you want the program to know its
name and respond to it. If PICKNAME is not defined, the
program will assume that it is called "flip".
SETFT Must be a function or macro with usage SETFT(file,name,var)
that will take an open file, a filename, and a variable
name, and set the timestamp of the file from the variable.
SIG_T If USE_SIG is defined, then SIG_T must be defined
(or typedef'd) to be the data type returned by
(*signal). Usually int or void.
SPEC_EXIT Like SPEC_INIT, but is called just before flip exits.
SPEC_INIT This is invoked to initialize flip. Should be defined to
be either a function call (with trailing semicolon) or
null string.
SGFTIME This must be a typedef for a data type suitable to store
file times.
USE_TABLE If this is defined, flip code will use a table look-up
to decide which characters should be considered binary.
See also BINCHAR.
ULTRIX_BUG At least one version of Ultrix chokes on a trailing "b"
in the mode string for fopen(). If ULTRIX_BUG is defined
no trailing "b" will be used.
USE_SIG If this is defined, then signal() will be used so flip
may trap user interrupts and delete temporary files.
If USE_SIG is defined, then SIG_T and INT_EXIT must also
be defined (below).
WILDCARD If this is defined, the function nextfile() will be called
to expand wildcards. If WILDCARD is not defined, no
wildcard expansion will be done and nextfile() is not
needed. For a description of nextfile() see turboc.c.
