Bug#760701: "make check" has runaway memory usage on arm64

Hi Ed,

> assumes char is signed... and, indeed, this seems to fix it:

Thanks, I have updated the Debian package and uploaded a new
version. Let us see how it works out.

Bug#760701: "make check" has runaway memory usage on arm64

[Edmund Grimley Evans]

The pattern of failures certainly looks like that of a program that
assumes char is signed... and, indeed, this seems to fix it:

- In io.web, change the return type of get() and peek() from char to int.

- In scan.web, change the type of prev_char, curr_char and next_char
from char to int.

Hi,

We can also see this on the Reproducible Builds project arm64
machines, eg.

Bug#760701: "make check" has runaway memory usage on arm64

[Steve McIntyre]

Package: 3dldf
Version: 2.0.3+dfsg-2
Severity: important

This might be related to #759696, not sure.

On arm64, I just killed the build of 3dldf when I saw that a test
process using 48GB of memory. The build log around this said:
