* Sort includes. Include <exit.h>, <unlocked-io.h>.Paul Eggert2004-04-121-30/+37
| | | | | | | | (specify_comparison_type): Don't report an error if the comparison type has already been specified the same way as this one. (usage): Mention exit status. (main): Adjust to latest gnulib c_stack_action calling conventions. (main): Adjust to latest version_etc calling conventions.
* (diag): Return void, not lin, since the returnPaul Eggert2004-03-121-60/+35
| | | | | | | | | | | value wasn't needed. All callers changed. (diag, diff_2_files): Use 'true' and 'false' instead of '1' and '0', when appropriate. (compareseq): Use lin const * local variables instead of lin *. Don't bother checking diag's return value. (shift_boundaries, build_reverse_script, build_script, diff_2_files): Use char arrays, not bool arrays, since sizeof (bool) might be greater than 1.
* (diff3.$(OBJEXT), diff.$(OBJEXT), sdiff.$(OBJEXT)):Paul Eggert2002-10-151-1/+1
| | | | | | | Rename from (misspelled) diff3.$(OBJECT), diff.$(OBJECT), sdiff.$(OBJECT). Patch by Paul D. Smith in <http://mail.gnu.org/pipermail/bug-gnu-utils/2002-October/003251.html>. Bug reported by Chris Bainbridge.

| | | | | | | (paths.h): Send output to paths.ht first, and then rename to paths.h at the end. This avoids problems if the disk is full. It also works around what appears to be a bug with GNU make -j (3.79.1); see <http://bugs.gentoo.org/show_bug.cgi?id=8934>.
