+Good places to get "support" functions:
+
+`libgnomesupport' is essentially a `glibc' emulation library, and hence
+`glibc' itself is a good source.  However, some of the functions cannot
+be easily ripped out and put here (esp. any of the stdio-derived
+functions).  Other places are:
+
+* libiberty from your friendly Cygnus source distribution, e.g.,
+  binutils, gdb.  The only caveat is that these cannot be used drop-in:
+  you have to remove references to other files in the Cygnus tree &c.

+* libit, which appeared briefly on ftp://alpha.gnu.org
+
+* Jim Meyering's collection from his `fileutils'/`sh-utils'/`textutils'
+  packages
