[R] Problem w/cygwin1.1 (maybe)

[Setzer.Woodrow@epamail.epa.gov]

I am using rw1001 on Windows 98.  I have a package that involves both c and
fortran code, which compiled successfully under cygnus b20.1 with Mummit Kahn's
port of gcc 2.95.2.  I have upgraded to the new net release of cygwin (version
1.1, including the recent cygwin package upgrade to 1.1.1).  Now when the dll
for my package is being created, I get the string of errors like:

[...]
gcc -mno-cygwin -mdll  -Wl,--base-file,odesolve.b -s  -o odesolve.dll odesolve.e
odesolve.a  -L/R/rw1001/src/gnuwin32  -lg2c -lR

/usr/lib/gcc-lib/i686-pc-cygwin/2.95.2/libg2c.a(fmt.o)(.text+0x9d): undefined

[...]

Presumably, somewhere I have configured either MkRules or my cygwin installation
incorrectly, but I cannot see where I've gone wrong.  I wonder if someone on the
list recognizes this error, or can give me some hints?  Thanks!
