Suppose you are making a shared library using

R CMD SHLIB foo.cc

If there is a file called foo.c in the same directory, then it will be used
instead.

faheem ~/scratch/r-base>R CMD SHLIB foo.cc
gcc-3.0 -I/usr/lib/R/include   -D__NO_MATH_INLINES -mieee-fp  -fPIC  -g -O2
-c foo.c -o foo.o
g++-3.0 -shared  -o foo.so foo.o   -L/usr/lib/R/bin -lR

This has been rather annoying for me, because I sometimes write C and C++
versions of the same program side by side and so the files have the same
name except for the extensions. It should be possible to fix it, though I
don't understand the relevant scripts enough to suggest a patch.

Note this bug has also been reported by me as Debian bug #184969. You can access
