Subject: Include canonicalize.h first, to test interface.
X-Git-Tag: CPPI-1_12~774
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=0d3649e30daa809ba2ed56508db98188797ad1c4;p=thirdparty%2Fcoreutils.git

Include canonicalize.h first, to test interface.
Include <stddef.h> unconditionally, since we assume C89 now.
All uses of PTR_INT_TYPE replaced by ptrdiff_t.
