Splendid!

"Run stat() before open() on some files to allow bailing out earlier":
Applied.

"Include getopt.h when getopt_long() is provided by the system": Applied.

"Unlink destination file before renames": Applied with commit message tweak.

"Introduce and use x_fmmap() and x_munmap()": Applied with commit
message tweak.

"Close file opened with gzdopen()": Applied.

"Duplicate path string inside find_executable_in_path() instead of
expecting caller to duplicate it before.": Applied with commit message
tweak.

"Close manifest files after reading/writing them": Applied.

"Implement is_absolute_path() helper function.": Applied with commit
message tweak.

"Implement compare_executable_name() helper function.": Applied with
commit message tweak.

"Implement is_full_path() helper function": This doesn't work if the
path is "../foo" or any other relative path other than "./foo". Doesn't
just searching for "/" or "\\" work on Windows too?

"Clear exit_functions after the exit functions have been called": Applied.

"Add a define for path delimiter": Applied. Also made CCACHE_EXTRAFILES
use PATH_DELIM.

"Use a temporary file for sed_in_place()": Applied.

"Allow testsuite to run on Windows": Applied.

"Win32 support": In compare_executable_name, you can use
x_asprintf(&tmp, "%s.exe", s2) instead. Otherwise, looks good to me.
