(PR#8017) build of REventLoop package crashes with 2.1 due

Full_Name: Richard Boyce
Version: 2.1.-1
OS: Debian testing/unstable
Submission from: (NULL) (128.95.123.29)


While building a custom package using a modified version of Duncan's 
REventLoop with R version 2.1 (Debian package r-base, r-base-dev) and R 
source from apt-get source 2.1.1 I get the following error:

$ R CMD build vjREventLoop
* checking for file 'vjREventLoop/DESCRIPTION' ... OK
* preparing 'vjREventLoop':
* cleaning src
* checking whether 'INDEX' is up-to-date ... NO
* use '--force' to overwrite the existing 'INDEX'
* removing junk files
* building 'vjREventLoop_0.2.tar.gz'

$ su
# R CMD INSTALL vjREventLoop_0.2.tar.gz
gcc -I/usr/lib/R/include    -I/usr/src/r-base-2.1.1/src/include -fPIC  -g -O2

ERROR: compilation failed for package 'vjREventLoop'
** Removing '/usr/local/lib/R/site-library/vjREventLoop'
** Restoring previous '/usr/local/lib/R/site-library/vjREventLoop'

*Build works correctly with R-2.0.0 installed from source* with
$ ./configure --prefix=/usr/local --enable-R-shlib
$ make
$ su
# make install

Inspection of Defn.h does not identify syntax error but I am not familiar with
all the details. Diff (probably not useful):
$ diff /usr/src/r-base-2.1.1/src/include/Defn.h
/opt/Downloads/r-cran/R-2.0.0/src/include/Defn.h
