The patches needed to run squid (a web proxy server/web accelerator) under cygwin have been integrated into the main cvs branch: squid 2.4 devel (from cvs) should configure and run OOTB on cygwin with the following additional requirements: cygwin1.dll 1.1.4 perl autoconf autoheader Anyone who has been trying the squid port based on my emails (about 2 months ago) and was using the squid-cygwin cvs branch should erase that source tree and get the squid HEAD from sourceforge or squid-cache.org.
