Summary: warning: "FWRITE" redefined ... error: _O_BINARY
undeclared
Product: PCRE
Version: N/A
Hardware: x86
OS: Windows
Status: NEW
Severity: bug
Priority: medium
Component: Code
Assignee: p...@hermes.cam.ac.uk

CC: pcre-dev@exim.org
I have built Alien::PCRE2, which is a Perl software package which automatically
downloads and builds PCRE2:
https://metacpan.org/pod/Alien::PCRE2
The build is successful on most platforms:
http://matrix.cpantesters.org/?dist=Alien-PCRE2+0.012000
Unfortunately, the build errors on Cygwin in Windows:
