		Windows-specific changes to R
		=============================

Pipe connections now work under RGui and embedded R.dll, although
slower than under Rterm, and as they run with no stdin or stdout to
inherit what you can do with them is limited.  They work better for
reading than writing.

The installer will no longer crash trying to install addons with a
long PATH and R_HOME not set.  Similarly, Rcmd accepts long paths.

Using Rcmd INSTALL with an incorrect path specification ending in \ no
longer runs amok.

Internal pager no longer fails when given a file of one line and no
line ending.

Hyperlinks to other packages in CHTML files launched by help() will
now work irrespective of the working directory (but like HTML, only
to packages in the same library).  The .chm files do need to be
re-built under this version.

help(, winhelp=TRUE) will now find alias topics as well as main items.

Hitting the total memory allocation limit set by --max-mem-size will
give a warning (and will usually also lead to an error, and that may
suppress printing out the warning).

There is a new make target test-Reg to run the regression tests (which
now do I/0, so might give different results on Windows).

Rcmd build with the latest tar.exe will exclude files as intended.

There are further improvements in the GUI console receiving output
(e.g. from tcltk interactive functions) during input.  If you can,
arrange to send output in a single piece, or at least a whole line at
a time (although partial lines will now work).  For example, don't use
print() but capture the output in a text connection and use something
like cat(paste(outlines, "", collapse="\n)) to output a single string.

The initial rescaling is no longer done for windows(rescale="fixed"),
and the scrollbars in that mode are more responsive but move the
viewport 20 pixels at a time.
