R help - Aug 2005 - Rgdal windows binary warning message

Hi all,
 
I just downloaded windows binaries of RGDAL (from
http://www.stats.ox.ac.uk/pub/RWin/bin/windows/contrib/2.1/) and installed.
 
I ran the example R_HOME\library\rgdal\R-ex\getPixmapGDAL.R and everything
seemed to work as expected. However I got the following warning message:
 
DLL attempted to change FPU control word from 8001f to 9001f
 
The R-help (?dyn.load) describes the problem as:
 
************************************
External code must not change the floating point control word, but
     many DLLs do so.  Common changes are to set it to use 53 bit 
     precision instead of R''s default 64 bit precision, or to unmask 
     some exceptions.  ''dyn.load'' detects such changes,  and
restores
     R''s control word to its default value of hex 8001F.   This may
     cause the DLL to malfunction; if so, it should be rewritten to
     save and restore the control word itself.  If ''warn.FPU''
is set to
     ''TRUE'' using the ''options'' function,  a
warning will be printed.
     (If the warning says that the control word was changed from some
     other value than 8001F,  please report the circumstances to the
     Windows maintainers:   that probably indicates an internal bug.)
 
************************************
 
Does anyone know if this is a major problem for reading and manipulating
image files using RDAL? And if so are there windows binaries which have
patched it up?
 
Thanks in advance
 
Tony

Hello every one--

My sincere apologies if I have missed something obvious, but I need  
to construct some multinomial logit models.  I remember using nnet  
for this in the past, but I am having trouble locating a OS X version  
of this (it's been a year or so since I had to use it). I found a   
Windows version, but when I try to install across platforms, it  
crashes R immediately--no error messages or anything helpful.  Can  
any one direct me to a repository, or alternatively, to another  
package readily available Mac side that can do simple multinomial  
logit models? This is basic survey data--nothing fancy needed.

All best,

Lisa

This is a consequence of how VC++ compiled gdal.  R is protecting 
itself against that.  Since R did not crash, there is nothing to worry 
about.
