Jonathan Wakely <redi at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Status|WAITING |NEW --- Comment #4 from Jonathan Wakely <redi at gcc dot gnu.org> --- gcc/Makefile.in has: # Install the include directory using tar. install-headers-tar: stmp-int-hdrs install-include-dir # We use `pwd`/include instead of just include to problems with CDPATH # Unless a full pathname is provided, some shells would print the new CWD, # found in CDPATH, corrupting the output. We could just redirect the # output of `cd', but some shells lose on redirection within `()'s (cd `${PWD_COMMAND}`/include ; \ tar -cf - .; exit 0) | (cd $(DESTDIR)$(libsubdir)/include; tar xpf - ) (cd `${PWD_COMMAND}`/include-fixed ; \ tar -cf - .; exit 0) | (cd $(DESTDIR)$(libsubdir)/include-fixed; tar xpf - ) # /bin/sh on some systems returns the status of the first tar, # and that can lose with GNU tar which always writes a full block. # So use `exit 0' to ignore its exit status. This doesn't require GNU tar though, just any tar, so I think I agree that it's just like cp and file and sed which are part of any unix-like environment. The prerequisites page is specifically saying that GNU tar is needed on some systems, for the reason Andrew stated above.
