 I found that return value of EUC-TW TO_LOOP is wrong.

 When it comes out of space to write converted string, it should return 
'__GCONV_FULL_OUTPUT', but EUC-TW TO_LOOP returuns '__GCONV_INCOMPLETE_INPUT'.
As a result, programs can not handle the error properly.

 Attached program tests this situation simply.  When output buffer
is insufficient, errno should set E2BIG, but the result will be
EINVAL when convert to EUC-TW.  While converting to EUC-JP, it returns 
E2BIG correctly.  Of course, both of case, it converts proper multibyte 
string, if output buffer is enough to write.
