Under Cygwin (i.e., Windows), you should create .dll files instead.

The -fpic options is unnecessary under Cygwin.

You are missing the "-lpostgres" option (and possibly the associated
"-L" option too) on the link command line. Unfortunately, the binary
package does *not* contain libpostgres.a. This is because the other
Unix platforms do not have such a file. Sigh...
The short-term workaround is to download the PostgreSQL source and build
libpostgres.a yourself. I need to think about the long-term solution...
