Subject: Provide a <sys/param.h> with MIN() and MAX()
X-Git-Tag: 0.10.0~23
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=480334080262a705bc029d0acb62d49900bfbe3c;p=thirdparty%2Flibbsd.git

Provide a <sys/param.h> with MIN() and MAX()

Windows doesn't provide <sys/param.h>. Several libbsd sources require it
for MIN(), and these are useful non-system-specific macros anyway.
