Why does -pedantic make long long an error in C++?

[John David Anglin]

Don't know but you can turn the error to a warning by adding
-Wlong-long, and make it go away completely with -Wno-long-long!
Addition of -ansi doesn't seem to change the behavior of g++
wrt to this error/warning.

Probably, a PR is needed.
