 Everything goes well until trying to compile fdmgr.cpp when I get the
set of messages below. Has anyone else seen this (and hopefully solved
it) ?

In file included from ../../../src/libCom/fdmgr/fdmgr.cpp:29:

What I usually do in situations like this is to issue the compile
command with -c changed to -E so I can see exactly what's getting passed
on from the preprocessor to the compiler. The offending line is:

fd_set fdSets[fdrNEnums];

This makes me think that the likely cause of the problem is that

1) fd_set is not typefed properly. (to check, run the output of the
'-E' compile through 'grep fd_set'.

OR

2) fdSets is being defined as a preprocessor macro somewhere in some
cygwin header file. About the only thing to do here is to 'grep fdSets'
on all the header files.
BTW -- is EPICS likely to work on win98???
