Problem w/cygwin1.1 (maybe)

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
I have had a lot of problems with the cygwin net releases, and their mailing list shows that I am not alone. The version of make up currently is broken (and they know the cause and have not re-made it) and there are further problems with the 1.1.1 DLL that mean that re-direction in Makefiles fails (and that is used extensively in the R Makefiles).

I wonder if someone on the list recognizes this error, or can give me some hints? Thanks!
Looks like you have the wrong libg2c.a in use, the cygwin not -mno-cygwin one. What do you have set as FLIBS in MkRules? In rw1001 it says #-L(directory where gcc-2.95-mingw-extra.tar.gz was uncompressed) FLIBS=-L/cygnus/cygwin-b20/mingw32/lib -lg2c I don't see any sign of pointing you at a particular lg2c (but do not know if that is needed under cygwin 1.1.1). It is pretty irritating that every time I `upgrade' cygwin something else breaks. For rw1010 we intend to support only the mingw32 compiler and a set of tools we will make available that we know works. For example, I compiled up a version of make 3.79 from the GNU make sources. The mingw32 compilers are just as easy to install and use, and they seem very stable.
