[Mingw-users] printf ' flag

[Gerald S. <gsh...@ca...>]

I want to comma separate an integer (ie 6,345,222 instead of 6345222), and 
according to the libc manual, GNU supports an extension whereby I can say 
printf("%'d", integer_variable), but for output I get 'd , i.e. the flag is 
not recognized, and it treats 'd as a literal string. I tried escaping the 
' "%\'d", to no avail. (fwiw, I get the same in cygwin's gcc).

Is it just me, or is this a known difference from gcc?
