[Dovecot] 0.9.10 and Cygwin

Has anybody succeeded in compiling 0.9.10 with Cygwin? I'm getting the following error:-

gcc -DHAVE_CONFIG_H -I. -I. -I../.. -g -O2 -Wall -W -Wmissing-prototypes -Wmissing-declarations -Wpointer-arith -Wchar-subscripts -Wformat=2 -Wbad-function-cast -c istream-file.c istream-file.c:57: conflicting types for _close' /usr/include/sys/unistd.h:148: previous declaration of _close' istream-file.c:129: conflicting types for _read' /usr/include/sys/unistd.h:153: previous declaration of _read' make: *** [istream-file.o] Error 1

Thanks
