Typo - recallocarray --> reallocarray
Found this apparent typo in the current code basis during my build as CC recallocarray.lo
and see #19 (comment 2018608)
A man libbsd
lists a "reallocarray(3bsd)" i.e. without a 'C' in "re_C_allocarray" instead.
I might provide a patchfile in due time...
Hope this helps.
