You missed my posts (earlier this week). The subject is:
"mingw-cross with R 2.4.x Re: [Rd] wine and build difference between 
R.2.4.0 and R 2.4.1 windows binaries?" which contains my notes on this 

Basically you need newer mingw than on Prof Ripley's web site (i.e.
you'll need to build mingw yourself), and as for the pcre error
in 2.4.0, you need to graft pcre from 2.4.1 back. Good luck.
