228 Cygwin is a Linux-like environment for Windows. It consists of two parts:
239 This should create two libraries called libpcre2-8 and libpcre2-posix. These
240 are independent libraries: when you link with libpcre2-posix you must also link
241 with libpcre2-8, which contains the basic functions.
