Changes in 1.3: Fixed a configure glitch in yesterdays version. Changes in 1.2: Fixes for using the latest Guile from CVS: no longer uses unquoted () for the empty list, uses gensym instead of gentemp. Installation scripts generated by newer autoconf and automake. Random changes to configure.in and Makefile.am. Changes in 1.1: tail-call-program no longer flushes output buffers, since it's incorrect after forking a child process. The buffers would probably be flushed in both parent and child, producing duplicate output. This affects other goosh procedures and macros indirectly. The internal procedures stdports->stdio, pipe-split-components and remove-dup-connections are no longer exported. autoconf and automake are used for installation.
