checkS3methods() change

Hi,
I'm using rw2000dev.exe (Win32) built on August 14.

If this isn't already planned, can I suggest that when
checkS3methods() (called by R CMD check) fails because of
a syntax error in a dependent package listed in the DESCRIPTION
file of the main package being checked, it would be nice if
checkS3methods() reported which dependent package caused it to
fail?

Running R CMD check on my package limmaGUI, revealed a syntax
error in one of limmaGUI's dependent packages, which turned out
to be the R2HTML package (after a bit of sleuthing).

Here's the syntax error in R2HTML, caused by the new parsing
rules for associative use of relational operators:

  x0 <- xm[okP] == 0 != (as.numeric(Cf[okP]) == 0)

The R2HTML package (version 1.3) was installed with:

install.packages("R2HTML")

trying URL `http://cran.r-project.org/bin/windows/contrib/2.0/PACKAGES'

Here's the tail of the R CMD check output for limmaGUI:
