+Although they were not defined as protypes in <b>pcre2posix.h</b>, releases
+10.33 to 10.36 of the library contained functions with the POSIX names

+earlier versions of PCRE2, which had only POSIX names. However, this has proved
+troublesome in situations where a program links with several libraries, some of 
+which use PCRE2's POSIX interface while others use the real POSIX functions. 
+For this reason, the POSIX names have been removed since release 10.37.
