[R] About building R1.6.1 on Cygwin

[Hisaji Ono]

Hello.

 For building REmbeddedPostgres in Omegat
project(http://www.omegahat.org/RSPostgres/) requiring PostgresSQL's libs,
I've tried to build R1.6.1 on Cygwin following the instruction of
http://www.stats.ox.ac.uk/pub/Rtools/ since full-spec PostgresSQL running on
Windows can run only on Cygwin environment,

 However I've got following error messages.

 make -C front-ends Rpwd
make[1]: Entering directory `/usr/src/R-1.6.1/src/gnuwin32/front-ends'
make -C ../fixed version
make[2]: Entering directory `/usr/src/R-1.6.1/src/gnuwin32/fixed'
sed -e 1d ../../../tools/GETVERSION > ../../../tools/GV
sh ../../../tools/GV > ../../include/Rversion.h
rm -f ../../../tools/GV

make Rpwd.exe

 Could you tell me any suggestion of building  R1.6.1 on Cygwin?

 Best Regards.
