[Rd] R + OS X + gcc 3.5 = not quite there ..

I tried to compile R (current R-patched to be more precise) with gcc 3.5 by Apple (which will be probably shipped with Tiger) and here's how far I got:

  1. compilation itself was fine except for one exception: ../../../../../../R-patched/src/library/stats/src/starma.c: In function `forkal': ../../../../../../R-patched/src/library/stats/src/starma.c:384: error: invalid lvalue in assignment

relevant code:

for (j = 0; j < nt; j++)
if(!ISNAN(tmp = G->resid[j])) { nu++; sigma2 += tmp * tmp; }

problem: ISNAN changed obviously as the pre-processing result shows:

  if(!(( ( sizeof ( tmp = G->resid[j] ) == sizeof(double) ) ? __isnand (

(double)tmp = G->resid[j] ) : ( sizeof ( tmp = G->resid[j] ) == sizeof( 
float) ) ? __isnanf ( (float)tmp = G->resid[j] ) : __isnan ( ( long 
double )tmp = G->resid[j] ) )!=0)) { nu++; sigma2 += tmp * tmp; }

fix: get the assignment out of ISNAN:
for (j = 0; j < nt; j++) {

     tmp = G->resid[j];
     if(!ISNAN(tmp)) { nu++; sigma2 += tmp * tmp; }

2) DYLD_LIBRARY_PATH shouldn't be too eagerly changed - R segfaulted with the default setting. Unfortunately it segfaulted in a weird place (in code responsible for loading a shared library somewhere in non-R code). Removing all unnecessary stuff (such as /usr/local) from the path helped (i.e. the path is now just ${R_HOME}/bin).

3) problem with saved images. I can't quite figure out this one: basically R isn't able to load images stored during the package installation phase. I get this error:
Error: bad restore file magic number (file may be corrupted)-- no data loaded

for example with stats:
> library(stats)

Error: bad restore file magic number (file may be corrupted)-- no data loaded
Error in library(stats) : package/namespace load failed

same if you try to load .../stats/R/all.rda manually. I put the rda file in http://www.rosuda.org/misc/all.rda (it comes from the stats package) for anyone who can have a look at it...

using save/load manually on arbitrary objects worked for me, however I don't know how to re-create the all.rda manually, so I'm stuck here. Any ideas?
