Hello PostgreSQL,
I found a way past the earlier problem and a new problem.
cygipc installed in to /usr/local/bin so I moved cygipc to
/cygwin/usr/local/bin.
./configure proceeded past the previous failure and produced
configure: error: ./src/backend/port/tas/dummy.s File not found
I did:
touch backend/port/tas/dummy.s
and ./configure ran to the end without visible error.
The touch suggestion came from an error report for PostgreSQL 6.5.2.
