Hi Allan,

I was wondering if you have any ideas about how we can overcome the 
limitation of toupper() function in libc w.r.t. Turkish language.
This is not a very important item according to my knowledge,but if we 
have any ideas that can be used ,it would be very helpful.
The issue details are as below,
(note that this is related to 
In case of Pardus linux ,Turkish version with XSane frontend, the 
backend does not output debug logs for some backends.
This is due to  limitation of toupper() function w.r.t.  character 'i' 
when locale is set to turkish.
As  toupper('i') is 'i' (i.e. still the small i) ,the SANE_DEBUG_RICOH  
etc would not work correctly.

Root cause:
Env variable set by user as mentioned in the man page is as below
     export SANE_DEBUG_RICOH=4

Sane's search logic's final string generated  for ricoh backend would 
be  SANE_DEBUG_RiCOH    --->note mismatch for i

As the code searches for incorrect env. variable, the debug level 
requested by user is ignored.

Transient conclusions:
Current known side effect of the issue is "debug logs will not be 
available for Turkish OS ,with XSane frontend ,for all the backends 
which have character i in their name"

1>Though I have grepped for getenv ,toupper calls in the backend code, I 
believe only the debug related env. variable is affected by language 
     However I could see SANE_CONFiG_DiR too somewhere in the log but 
could not confirm the side effects due to lack of knowledge of the 
entire code.
     If it's only related to debug logging and nothing else serious we 
can ignore this issue at the moment.
2>As I am not sure about the other similar scenarios, if necessary I can 
send a patch specific to turkish language.
     As I am not an expert on the language I guess the changes would be 
somewhat hardcoded for character i and local TR.If there is any turkish 
member in the group,it would be very much helpful.

Sorry for bugging you with such items when there are many imp patches to 
be covered but just......
