* gcc.c (SWITCH_CURTAILS_COMPILATION): Definition.
        (DEFAULT_SWITCH_CURTAILS_COMPILATION): True for options -S and -c.
        (process_command): If HAVE_EXECUTABLE_SUFFIX is defined then scan
        command line arguments to see if an executable is not being
        created, and if so - do not append the suffix.

@findex SWITCH_CURTAILS_COMPILATION
@item SWITCH_CURTAILS_COMPILATION (@var{char})
A C expression which determines whether the option @samp{-@var{char}}
stops compilation before the generation of an executable. The value is
boolean, non-zero if the option does stop an executable from being
generated, zero otherwise.
By default, this macro is defined as
@code{DEFAULT_SWITCH_CURTAILS_COMPILATION}, which handles the standard
options properly. You need not define
@code{SWITCH_CURTAILS_COMPILATION} unless you wish to add additional
options which affect the generation of an executable. Any redefinition
should call @code{DEFAULT_SWITCH_CURTAILS_COMPILATION} and then check
for additional options.
