@file{libgfortran/io/unix.c:fd_truncate}; i.e.@: @code{ftruncate} or
@code{chsize}.
@item fenv
Target provides @file{fenv.h} include file.
@item fenv_exceptions
Target supports @file{fenv.h} with all the standard IEEE exceptions
and floating-point exceptions are raised by arithmetic operations.
@item freestanding
Target is @samp{freestanding} as defined in section 4 of the C99 standard.
Effectively, it is a target which supports no extra headers or libraries
