This includes the compilers.html and index.html file. I also threw in a slight formatting change in the thanks file.

## To build:
|
|
|
|
``` <!---sh-->
|
|
make all
|
|
```
|
|
|
|
**NOTE**: we **FORCE** disable the optimiser due to a funny problem with different
|
|
compilers and systems. See below and [compilers.html](compilers.html) for details.
|
|
|
|
There is an [alternate version](#alternate-code). The reason is a funny problem:
|
|
in modern systems, depending on the platform, compiler and whether or not the
|
|
optimiser is enabled, it might work with one compiler but non the other. But
|
|
then if you swap the optimiser state the compiler that worked would no longer
|
|
work and the compiler that did not work would. We describe this in more detail
|
|
in [compilers.html](compilers.html) and we encourage you to read it for
|
|
entertainment if nothing else.
|
|
|
|
|
|
## To use:
|
|
|
|
``` <!---sh-->
|
|
./marshall
|
|
```
|
|
|
|
|
|
## Alternate code:
|
|
|
|
Due to the different [conflicting problems](compilers.html) with `gcc` and
|
|
`clang`, we offer the problematic code as an alternate version whereas
|
|
[marshall.c](%%REPO_URL%%/1986/marshall/marshall.c) has both the loop (that
|
|
turned into an infinite loop) commented out and the complicated arg to `_exit(2)`
|
|
commented out, changing the value passed into `_exit()` to `1`.
|
|
|
|
|
|
### Alternate build:
|
|
|
|
To see if your compiler has the problems noted above and in
|
|
[compilers.html](compilers.html), first build the alternate code:
|
|
|
|
|
|
``` <!---sh-->
|
|
make alt
|
|
```
|
|
|
|
|
|
### Alternate use:
|
|
|
|
Once the alternate code is built, see if your compiler has the problem:
|
|
|
|
``` <!---sh-->
|
|
./marshall.alt
|
|
```
|
|
|
|
Does it work in your system? That is does it print the text only once and does
|
|
it not enter an infinite loop? In other words, does it print the text _exactly
|
|
once_ and then exit, without dumping core?

## Judges' remarks:
|
|
|
|
This program prints the name of the picture. The layout is somewhat
|
|
pretty though it is not the usual sort of output one would expect
|
|
from printing a program!
|
|
|
|
This program was selected for the 1987 t-shirt collection.
