Cannot insert sharps

[Matthieu Pupat]

     Hello,

I try a simple macro that prepone a sharp (#) before names beginning 
with i or o and quoting other names :

define(`QuoteVariable', `ifelse(substr($1,0,1), i, #$1, 
ifelse(substr($1,0,1), o, #$1, "$1" ) ) ')

QuoteVariable(iTestI);
QuoteVariable(oTestO);
QuoteVariable(lTestL);

If I replace my sharps by A for example this works fine.

There I get the message:

m4: file "Test.m4": line 5: EOF in arg list


Is this a bug ?
What can I do to get rid of this ?
