regarding format specifier %lg in sscanf

I am reading a character array which has value 9.9999 into a double variable using sscanf. the statement is like this:
double dvar1;
char cvar[256] = "9.9999";
sscanf(cvar, "%lG", &dvar);
printf("%lG", dvar);

now when I run the program on a solaris machine using sunwspro CC, it works fine, but on gcc or pgcc on interix machine does not output the value correctly. I have to use the format specifier %lg for gcc on interix to get the output correctly. Can anybody explain why is it like this? is %lG not supported in gcc/pgcc, I can see its use in printf but not in scanf.

I don't think the uppercase G conversion specifier is Standard C. In my opinion, you should have been using "%lg" from the beginning.
