include/stubs-bootstrap.h

   1 /* Placeholder stubs.h file for bootstrapping.
   2
   3    When bootstrapping a GCC/GLIBC pair, GCC requires that the GLIBC
   4    headers be installed, but we can't fully build GLIBC without that
   5    GCC.  So we run the command:
   6
   7       make install-headers install-bootstrap-headers=yes
   8
   9    to install the headers GCC needs, but avoid building certain
  10    difficult headers.  The <gnu/stubs.h> header depends, via the
  11    GLIBC subdir 'stubs' make targets, on every .o file in GLIBC, but
  12    an empty stubs.h like this will do fine for GCC.  */
