[R] Problem with making dll under Windows

[Uwe Ligges]

Please check that you have installed a suitable environment (tools, 
compiler etc.) as mentioned in the R Installation and Administration 
manual. Öooks like your version of Perl is corrupted.

I got with your C program:

d:\aaa>R CMD SHLIB dmypow.c
making dmypow.d from dmypow.c
gcc   -It:/R/include  -Wall -O3 -std=gnu99   -c dmypow.c -o dmypow.o
windres -I t:/R/include  -i dmypow_res.rc -o dmypow_res.o
gcc  -shared -s  -o dmypow.dll dmypow.def dmypow.o dmypow_res.o 
-Lt:/R/bin    -lR
