[Rd] RCMD SHLIB == Couldn't reserve space for cygwin's heap, Win32 ?

I've been trying to create/load/call a dll from R-1.8.1 on Windows without
much success. I've been able to at least load the library on FreeBSD
(1.8.1). I've been able to perform this before using DLL that weren't
created using RCMD SHLIB, but simply compiling under MS DevStudio.

C:\optflikam>

 Then from R, I've tried to simply load the library and R crashes and I
can't load the DLL. I keep getting the following error:
> dyn.load( "optflikam.dll" )      5 [main] ? 4012 init_cheap: Couldn't reserve space for cygwin's
heap,
Win32 error 487

BaseAddress 0x61670000, RegionSize 0x1050000, State 0x10000

I thought it might have something to do with the compiler, so I looked at
the version of cygwin's gcc:

C:\optflikam>gcc --version

Is this the problem and has anyone else run into this? I've never seen this
meesage before.

I'd worry about this warning:  stdcall is the name of a calling
convention, so this is likely some code being misinterpreted pretty
badly.
><built-in>:61:1: warning: this is the location of the previous
definition

This also looks like trouble to me...

Your DLL expects to be running under Cygwin.  R doesn't run Cygwin; we
use the MinGW compiler.   DLLs produced by all sorts of other
compilers do work, so you might be able to get Cygwin to work if you
try hard enough -- but it's probably easier to install MinGW.  See
mingw.org for downloads, etc., and the readme.packages file in the
Windows installation for our recommended toolsets.
