Note that this implies that packages which unconditionally use R_VERSION
or R_Version (note that R-exts in facts recommends

  #if defined(R_VERSION) && R_VERSION >= R_Version(0, 99, 0)

will fail to install under the current r-devel.

These packages seems to be

	Matrix
	RArcInfo
	RODBC
	XML
	chron
	gafit
	mda
	odesolve

(two of which I happen to maintain myself ...) as well as the Omegahat
packages

	CORBA
	RGnumeric
	RSPerl
	RSPython
	SJava
	SNetscape
	SXalan
	Slcc
	Sxslt

It would be great if we could have updates of these packages in the near
future, either via following the recommended procedure from R-exts or,
perhaps preferably, removing the pre-1.2.0 compatibility code and adding

	Depends: R (>= 1.2.0)

in the package DESCRIPTION file.

Thanks
