That way, for example, if @file{config.h} defines @samp{restrict} to be the empty string on a pre-C99 host, or a macro like @samp{_FILE_OFFSET_BITS} that affects the layout of data structures, the definition is consistent for all include files. -Another reason why @file{config.h} must be included before any other -include file is that it may define macros like @samp{_GNU_SOURCE} -or @samp{_FILE_OFFSET_BITS} which, on glibc systems, have an effect only -if defined before the first system header file is included. +Also, on some platforms macros like @samp{_FILE_OFFSET_BITS} and +@samp{_GNU_SOURCE} may be ineffective, or may have only a limited +effect, if defined after the first system header file is included.
