Each program-name variable should come with an options variable that is
used to supply options to the program. Append @samp{FLAGS} to the
program-name variable name to get the options variable name---for
example, @code{BISONFLAGS}. (The name @code{CFLAGS} is an exception to
this rule, but we keep it because it is standard.) Use @code{CPPFLAGS}
in any compilation command that runs the preprocessor, and use
@code{LDFLAGS} in any compilation command that does linking as well as
in any direct use of @code{ld}.
example, @code{BISONFLAGS}. (The names @code{CFLAGS} for the C
compiler, @code{YFLAGS} for yacc, and @code{LFLAGS} for lex, are
exceptions to this rule, but we keep them because they are standard.)
Use @code{CPPFLAGS} in any compilation command that runs the
preprocessor, and use @code{LDFLAGS} in any compilation command that
does linking as well as in any direct use of @code{ld}.
If there are C compiler options that @emph{must} be used for proper
compilation of certain files, do not include them in @code{CFLAGS}.
