Subject: Conditional sys/sysmacros.h inclusion
Date: Mon, 13 Mar 2017 12:58:38 +0100	[thread overview]
Message-ID: <20170313115838.GA28761@t450.itgeo.fhwn.ac.at> (raw)

Hi,

please find attached a diff that makes the inclusion of the sys/sysmacros.h
header file conditional. I noticed it on OpenBSD which has no sys/sysmacros.h,
so compilation fails there.

Best regards,
Ingo
