OK. Thank you.
Here it is.
Could you push it to appropriate people?

Attaching test for it also.
To do tests:
- copy patched filename_cmp.c and filenames.h to new dir
- touch  safe-ctype.h
- create  hashtab.h with
typedef int size_t;
typedef int hashval_t;
#define TOLOWER(c) (c)
This is enough for me to test it on cygwin32. It may be that other platforms 
will require another fake includes.
- gcc -O2 filename_cmp.c main.c -o test1

Best regards
Vladimir
