Andy,
Are you talking about C or Fortran code here? Fortran has `intrinsics', C
does not AFAIK.
I think we do pretty strict checking of C code in CRAN packages, and I
have not encountered problems with other C compilers (e.g. the Solaris
ones). There used to be issues with CRLF line endings,
Dear DevelopeRs,
I'd like to ask those who develop R packages with compiled code to please
try avoiding dependency on GCC (gcc/g77/gfortran/g++) specific features in
the code, for the simple reason that there are non-GCC compilers out there
that might choke on such features.
I found this out back
