Bug 000182

When Created: 10/23/1997 20:20:45
Against DJGPP version: 2.01
By whom: eldredge@ap.net
Abstract: scanf() with %LG specifier doesn't read a long double
When using the scanf() family with a %LG format specifier, a `double'
is read instead of a `long double' as the docs claim.
Note that this is apparently a DJGPP extension and not ANSI std.

Workaround added: 10/23/1997 20:22:34
By whom: eldredge@ap.net
Use `%Lg' or `%Le' (oh yeah, it also happens for `%LE') instead.

The bug was real, but %LG is NOT a DJGPP extension, contrary to what
Nate says: it's part of the ANSI C Standard.

Fixed in version on 04/13/1999 12:00:50
