__getreent undefined on linux app build

[geneSmith]

I have tried to build a linux app (actually a app and a shared library) 
that was made for linux and works there under cygwin. Was hoping for 
minimal changes. First off, it seemed that I had to tell the linker the 
c library name with -lc. That got rid of a ton of undefined references. 
However, it still has undefined reference to __getreent is every file 
when linking the shared library.

From reading this list, I see that __getreent comes from the 
cygwin1.dll at run time. I had more than cywwin1.dll on my system from 
misc apps and renamed them and rebooted. Still get the link error.

I assume you can build a shared library (the docs. only seem to talk 
about dll's) and that a shared library can call a function in the cywin dll.

Someone also suggested using the latest snapshot to fix this type of 
problem. The other day when I tried to get a new app with setup.exe it 
automatically loaded the "latest" gcc.

Here is my uname -a.  If cygcheck -srv is needed, let me know.
CYGWIN_NT-5.0 04J005 1.5.10(0.116/4/2) 2004-05-25 22:07 i686 unknown 
unknown Cygwin
