Subject: [PATCH] mailmap: work around implementations with pure inline strcasecmp
On some systems (e.g. MinGW 4.0), string.h has only inline
definition of strcasecmp and no non-inline implementation is
supplied anywhere, which is, eh, "unusual". We cannot take an
address of such a function to store it in namemap.cmp.
Work it around by introducing our own level of indirection.
