Hello, For your information, let me explain about regexp support.

The regexp subdirectory was introduced to support POSIX regexp functions on Windows. The intention is providing same behavior among GnuPG on different Operating Systems. Historically, regexp in OpenPGP had been not supported by Windows versions of GnuPG; In the past, when a user switched his Operating System from common POSIX one to Windows, it stopped working. If it is only for Debian, possibly, we can simply use POSIX regexp functions in the C library, perhaps. There are corner cases for regexp matching among different regexp functions support and Unicode versions. Strictly speaking about a data specification, it would be more acculate to specify exact Unicode version explicitly in the OpenPGP standard. --
