The above implies that either libcygipc.a is not installed (in the
normal place) on your system or that the default library search path has
changed in the gcc 3.x package.

Please perform the following and report back to the list:

$ ls -l /usr/local/lib/libcygipc.a
-rwxrwxrwx 1 Administ Domain U 26912 Nov 26 2001 /usr/local/lib/libcygipc.a

$ echo 'main(){return(0);}' >conftest.c
$ gcc -v -o conftest conftest.c -lcygipc
Reading specs from /usr/lib/gcc-lib/i686-pc-cygwin/2.95.3-5/specs
gcc version 2.95.3-5 (cygwin special)
[snip]
/usr/lib/gcc-lib/i686-pc-cygwin/2.95.3-5/collect2.exe -Bdynamic --dll-search-prefix=cyg -o conftest.exe /usr/lib/crt0.o -L/usr/local/lib -L/usr/lib -L/usr/lib/w32api -L/usr/lib/gcc-lib/i686-pc-cygwin/2.95.3-5 /mnt/c/DOCUME~1/jatis/LOCALS~1/Temp/cchqAaau.o -lcygipc -lgcc -lcygwin -luser32 -lkernel32 -ladvapi32 -lshell32 -lgcc

Note that I'm still using the gcc 2.95.3-5 package and with this package
"-L/usr/local/lib" is automatically passed during linking. Maybe this
is not the case in the gcc 3.x package?
