[R] error in gmake CrossCompileBuild

[Steve Dutky]

Dear all,

I expect that I am on thin ice trying to build this on 
freeBSD 4.10, however, after tweaking Makefile-rcb v11Oct04
/* MAKE=gmake; MINGW_CROSS = mingw-cross4 */, I encounter:

mingw32-gcc -isystem ~/RCrossBuild/cross-
tools/mingw32/include -O2 -Wall -pedantic -I../include -I. -
DHAVE_CONFIG_H -DR_DLL_BUILD  -c dynload.c -o dynload.o
dynload.c: In function `R_loadLibrary':

gmake[2]: Leaving directory `~/RCrossBuild/WinR/R-

I see _controlfp is declared in ~/RCrossBuild/cross-
tools/<snip>/include/float.h but does not appear to be 
defined elsewhere.

Any advice greatly appreciated.  

Thanks, Steve Dutky
