Dear developers, is there (already) a platform-independent way for (temporarily!) changing the fpu control word? More precisely: I am looking for functions (accessible from C code in R packages) which read and write the fpu control word on x86 cpus (and cause no harm otherwise), because I need to (temporarily) turn off internal 80-bit precision for some algorithms relying on 64-bit IEEE

...en dyn.load and run: > dyn.load("flipme.so") > .C("flipme") Process R floating point exception at Mon Nov 18 17:41:50 2002 The debugger tells me its the printf line that kills it. Anyone have an idea what's going on here? I've tried a few things: * using _FPU_GETCW I've determined that R hasn't changed the control word from the system default. * I wrote a short main program that used dlopen() to call flipme - and it worked fine, so the problem isn't intrinsic to dynamically loaded code. * the author of the triangle package has put this in the...

A program I'm running requires a patch to be installed, I successfully downloaded the source and applied the patch to the source. How do I compile this into a wine build I can use now? The documentation on the wiki doesn't help that much, I'm quite new to all this.
