At www.g95.org, but I found no installation instructions relevant to
Windows. Some comments at the end of this message.

Here is an example src/Makefile.win for a package called testf95 that uses
F95/F90 only.
% cat testf95/src/Makefile.win
DLLNAME=testf95 # will not be needed in 2.2.0
include $(RHOME)/src/gnuwin32/MkRules
F90SOURCES=$(wildcard -f *.f90)
F95SOURCES=$(wildcard -f *.f95)
OBJS=$(F90SOURCES:.f90=.o) $(F95SOURCES:.f95=.o)
G95=c:/packages/g95/bin/g95
MINGW=c:/packages/gcc-3.4.4/
.SUFFIXES: .f90 .f95
.f90.o:
$(G95) -c $< -o $@
.f95.o:
$(G95) -c $< -o $@
## at least on my setup, G95 is not searching MinGW libs.
DLL=$(G95) -L$(MINGW)/lib
all: $(DLLNAME).dll
## Rules copied from MakeDll
RCNAME=${DLLNAME}_res
RCOBJ=$(RCNAME).o
RESFLAGS=--include-dir $(RHOME)/include
$(DLLNAME)_res.rc:
@PERL5LIB=$(RHOME)/share/perl perl
$(RHOME)/src/gnuwin32/makeDllRes.pl $(DLLNAME) > $@
$(DLLNAME)_res.o: $(DLLNAME)_res.rc $(RHOME)/include/Rversion.h
$(DLLNAME).a: $(OBJS)
$(DLLNAME).dll : $(DLLNAME).a $(RCOBJ)
It works for me, but do be aware that it will depend on the
fine details of how your MinGW/G95 tools are installed. I had to copy
dllcrt2.o from MINGW/lib to
C:/packages/g95/lib/gcc-lib/i686-pc-mingw32/4.0.1 since the paths are
processed after that file. It is probably better to fiddle with the specs
file.
