Current trun, rev. 117801, fails to build (I tried on MSYS2-MinGW64) 
with this compiler error:

gcc -std=gnu99  -c -mtune=generic   -DUSE_CRT_DLL=1 -I /tmp/emacs/nt/inc

 fileio.c
fileio.c: In function 'Fexpand_file_name':
fileio.c:1345:26: error: 'aidr' undeclared (first use in this function)
      newdirlen = strlen (aidr);
                          ^
fileio.c:1345:26: note: each undeclared identifier is reported only once 
for each function it appears in


maybe this change was the origin of failure:

2014-09-01  Dmitry Antipov  <xyz <at> xyz>

	Avoid extra calls to strlen in filesystem I/O routines.
	* fileio.c (Fexpand_file_name): Avoid calls to strlen if
	the length of 'newdir' is known or may be precalculated.
	(file_accessible_directory_p): Prefer to pass Lisp_Object,
	not 'char *', and so use precalculated length.
	(Ffile_accessible_directory_p):
	[...]


Ciao,
 Angelo.
