fts: reduce two or more trailing slashes to just one, usually * lib/fts.c (fts_open): Upon initialization, if a name ends in two or more slashes, trim all but the final one. But if a name consists solely of two slashes, don't modify it. If it consists solely of three or more slashes, strip all but one. This is part of the solution to a minor problem with rm: it would print a bogus ELOOP diagnostic when failing to remove the slash-decorated name of a symlink-to-directory: $ mkdir d && ln -s d s && env rm -r s/ rm: cannot remove 's': Too many levels of symbolic links With the change below and a trivial don't-trim-trailing-slashes adjustment to remove.c, it does this: $ env rm -r s/ rm: cannot remove 's/': Not a directory Improved by: Eric Blake

Description:
An <stdarg.h> that conforms to C99.

Files:
lib/stdarg.in.h
m4/stdarg.m4

Depends-on:
include_next

configure.ac-early:
dnl Some compilers (e.g., AIX 5.3 cc) need to be in c99 mode
dnl for the builtin va_copy to work.  With Autoconf 2.60 or later,
dnl gl_PROG_CC_C99 arranges for this.  With older Autoconf gl_PROG_CC_C99
dnl shouldn't hurt, though installers are on their own to set c99 mode.
gl_PROG_CC_C99

configure.ac:
gl_STDARG_H

Makefile.am:
BUILT_SOURCES += $(STDARG_H)

# We need the following in order to create <stdarg.h> when the system
# doesn't have one that works with the given compiler.
