Many thanks to everybody for the valuable answers. Several people (Benjamin and Ivan) pointed to the lack of portability due to the "-Wno-cast-function-type" flag. I have changed this.
Further, as suggested by Benjamin, I also added the " -DNDEBUG" flag. Consequently, there is no assert call anymore when compiling with gcc under Linux. Ivan suggested that the forbidden exit/abort calls might be caused by linking the R package with -static-libstdc+. I have now removed this but I am still getting the " Found '_exit'" etc. notes. It is also unclear to me why these exit / abort symbols are only found under Windows / MinGW and not under Linux. I agree with Dirks assessment. It seems that the bottom line is that it is very difficult to find the exit / abort calls. Very unfortunate...
