the print state representation: Don't use a tail array for
recording of circular references. Resizing of the print state
structure invalidates the print state pointer. To avoid passing
around an indirect print state reference to all printing
functions, we instead let the print state reference a resizable
vector.
scm_iprin1. Removed prototype for scm_prlist.
* print.c, print.h: Closures now print like #<procedure foo (x)>.
People who whish to see the source can do `(print-enable 'source)'.
Removed #ifdef DEBUG_EXTENSIONS.
main #include path; put most of them in a subdirectory called
'libguile'. This avoids naming conflicts between Guile header
files and system header files (of which there were a few).
* Makefile.in (pkgincludedir): Deleted.
(innerincludedir): New variable; this and $(includedir) are enough.
(INCLUDE_CFLAGS): Search for headers in "-I$(srcdir)/..".
(installed_h_files): Divide this up. Now this variable lists
those header files which should go into $(includedir) (i.e. appear
directly in the #include path), and ...
(inner_h_files): ... this new variable says which files appear in
a subdirectory, and are referred to as <libguile/mumble.h>.
(h_files): List them both.
(install): Create innerincludedir, not pkgincludedir. Put
the installed_h_files and inner_h_files in their proper places.
(uninstall): Corresponding changes.
