There maybe a spelling mistake, which in "check_func_headers sys/mman.h mmap".
It looks like should be "sys/mmap.h"
Thanks

Subject: [FFmpeg-devel] [PATCH] configure: Check for the header sys/mmap.h
when checking for mmap
Whenever mmap is used, we include sys/mmap.h unconditionally
within HAVE_MMAP ifdefs.
When building for a system (e.g. mingw) that normally lacks the
mmap function, but if building with profiling enabled, the
profiling runtime which gets linked in in each test executable,
can contain a function named mmap, causing stray detection of it.
This fixes an issue reported at
https://github.com/mstorsjo/llvm-mingw/issues/390.
