fgetc-usage causing infinite-loop on linux-ppc

[Philipp Schmidt]

The usage of fgetc, reading fgetc into an unsigned char causing an
infinite loop because eof iss too large for an unsigned char

the following patch solves the problem:

diff -r hugs98-Dec2001/src/input.c hugs98-Dec2001.fixed/src/input.c
515,516c515,517
<         lineBuffer[lineLength] = fgetc(inputStream);
<         if (lineBuffer[lineLength] == EOF)
---
>       int c = fgetc(inputStream);
>         lineBuffer[lineLength] = c;
>         if (c == EOF)

AVE!
