The macro FILENAME_NORMALIZE doesn't look necessary. I would prefer
use filename_normalize directly, just as filename_cmp is used in GCC
rather than FILENAME_CMP

Likewise. Change to lower case file name.

Redefining function names is easy to be confusing. At least I went up
and down several times to understand difference of two functions. I
feel it much clear to define a single filename_normalize, and then use
HAVE_DOS_BASED_FILE_SYSTEM to inline additional stuff for DOS into
this function. Like
filename_normalize (char *fn)
{
...
#ifdef HAVE_DOS_BASED_FILE_SYSTEM
// Additional work that your current DOS version does, basically
moving fn if needed.
#endif
... // Rest of what you have now
}

Fix wrong indent at continue.
Also it normalize filename like:
c:\abc\ into c:/abc\
The ending \ isn't normalized. Need to refine logic here to handle this case.
+#ifdef HAVE_DOS_BASED_FILE_SYSTEM
+void
+filename_normalize (char *fn)
+{
+ if (IS_DIR_SEPARATOR (fn[0]) || ! IS_ABSOLUTE_PATH (fn))
+ /* Absolute path in Unix style or relative path */
+ filename_normalize_unix (fn);
+ else if (fn[1] != '\0')
+ filename_normalize_unix (fn + 2);
+}
+#endif
+
Inline into unified version of filename_normalize

It will be more robust to check if fn is NULL at function entry. By
doing so, you can remove the if (pwd) condition in getpwd.c

All code inside {} should be two more spaces indent here. And remove if (pwd).
