Hi,
I have the same problem and, at a first look, the issues reported by the
CRAN checks seemed easy to fix. However, after checking it again locally
and on http://win-builder.r-project.org it appeared that GCC 4.9.3
(Windows, Rtools 3.4), same also on win-builder reports even more
issues, especially legacy Fortran (mainly Roger's #2 and #3), but also
"warning: ISO C forbids conversion of object pointer to function pointer
type"
The latter results from using pointers returned by R_ExternalPtrAddr()
for calling user-defined functions in DLLs, cf. the following thread
from the very beginning:
https://stat.ethz.ch/pipermail/r-devel/2004-September/030792.html
What is now expected to do?
1. Is it really the intention to start a complete rewrite of all legacy
Fortran code?
2. Is there now a better way for calling user functions than
R_ExternalPtrAddr()?
Many thanks for clarification,
Thomas

Hi Kurt,
I have started to look into this, and I need some guidance about how to
prioritize my repairs. There are basically 4 categories of warnings from
gfortran’s pedantic critique of my packages:
1. Some errant tab characters it doesn’t like,
2. Too many or too few continue statements
3. Horrible (and obsolescent) arithmetic and computed gotos
4. undeclared doubles and dubious conversions
The last category seems relatively easy to fix and is potentially
important, but the others seem more difficult to fix and altogether
less important. The goto issues are all in code that has been written
long ago by others and imported, e.g. Peyton and Ng’s cholesky.f.
I’m very reluctant to mess with any of those gotos. The fact that
they were declared obsolete long ago doesn’t mean that gfortran
has any intention of not supporting these constructs in the future,
does it?
Before devoting more time and energy, which is in short supply
lately, I like to hear what others are thinking/doing about all this,
so I’ll copy this to r-devel.
All the best,
Roger

Dear maintainers,
This concerns the CRAN packages

Using gfortran with options -Wall -pedantic to compile your package
Fortran code finds important problems, see your package check pages for
more information.
Can you please fix these problems as quickly as possible?
Best
