Here's the result:

$ gcc -mno-cygwin try_ansi.c=20
$ ./a.exe=20
AreFileApisANSI 1
$=20

Well, that's in EUC-KR and CP949.  CP949 has some more characters
defined in the empty areas of EUC-KR.  The directory name I used,
``=C7=D1=B1=DB'', which is pronounced ``hangeul'' and means Korean (written
language) in Korean, is consisted of two characters:
 U+D55C: Hangul syllable Hieuh A Nieun,
 U+AE00: Hangul syllable Kiyeok Eu Rieul.
(Perhaps, you may be able to find it from Windows charmap)
Neither character is in CP949's extension, so they have identical values
in both EUC-KR and CP949 encoding.

Yes, you gave me the identical numerical value I use.=20=20
Running, `echo -n =C7=D1=B1=DB | od -x -` tells me:
0000000 d1c7 dbb1

Now, `echo -n =C7=D1=B1=DB | iconv -f euc-kr -t utf-8 | od -x -` tells me:
0000000 95ed ea9c 80b8

Yes, it's in EUC-KR (or CP949 equivalently in this case).  I don't use
unicode environment yet.  Actually, I don't know how to change encoding
from Windows.  Korean version of Windows just uses CP949 as default.

Looks like od's output is in little-endian.  This identifies them as
U+D55C and U+AE00, `echo -n =C7=D1=B1=DB | iconv -f euc-kr -t ucs-2 | od -x=
 -`:
0000000 5cd5 00ae


> Thanks for your help

My pleasure. :)


BTW, is there any reason you not sending your msgs to cygwin ML?
If not, I'll just keep Cc'ing to it.
