gfortran Makefile for windows
I am unaware that gfortran or gcc4 exist as a MinGW binary for Windows. You mention Cygwin, but that is not a supported platform for R. There is a g95 binary for Windows. You can find how to link on Windows from the sources: most of the rules are in src/gnuwin32/MkRules. I suspect all you need is to set pkgname-DLLLIBS appropriately. I don't see that you need a Makefile: a Makevars file would suffice and avoid your hardcoding so many OS-specific features. In any case it seems to me that in general you need to link against the Fortran libraries: you may get away with it on MacOS, but you will not on Windows. Support for F95 files is planned for R 2.3.0, but depends on being able to differentiate F77 and F95 sources where needed (most platforms). Meanwhile we will try to add an example to the R-admin manual for 2.2.0.

I'm porting a package that I've worked on for OS X to Windows.
The package is written in F95 so I need to compile it with gfortran
and link it with gcc4.
I've been trying to build an R with gcc4 without luck so far. If there is
a binary of such a thing info would be appreciated.
This package requires a Makefile. My question is, how can I find out
(or what is), the link command?
Here is the OS X Makefile:
RLIB_LOC=${R_HOME}
F90_FILES=\
class_data_frame.f90 \
class_old_dbest.f90 \
class_cm_data.f90 \
class_cm.f90 \
class_bgw.f90 \
class_cm_mle.f90 \
cme.f90
FORTRAN_FILES=\
dgletc.f \
dglfgb.f\
dglfg.f\
dmdc.f\
mecdf.f
%.o: %.f90
gfortran -c -g $<
%.o: %.f
gfortran -c -g $<
bpkg.so: $(F90_FILES:%.f90=%.o) $(FORTRAN_FILES:%.f=%.o)
gcc -Wall -bundle -flat_namespace -undefined suppress -L/sw/lib
-L/usr/local/lib -o $@ $^ \
-L$(RLIB_LOC)/lib -lR
###EOF####
The -L lib dirs are not correct. On a *nix platform I would do something
like this
sh -x R CMD SHLIB ...
to get at the R internal link information but I can't get that to work on
Cygwin.
