Subject: syscall: set default constants for Inline::C platforms
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=832556492d3b94f9cadf9a4d249b519f30bae64d;p=thirdparty%2Fpublic-inbox.git

syscall: set default constants for Inline::C platforms

This fixes compile errors on platforms we can't explicitly
support from pure Perl due to the lack of syscall stability
guarantees by the OS developers.
