Compiling the above program from DOS under the name 'union.c' produced
the following results:

[WIN] D:\TEMP>gcc -Wall -O -g -o union.exe union.c
union.c: In function `main':
union.c:13: warning: int format, long int arg (arg 2)
[WIN] D:\TEMP>union
8

The warning is not major (you should specify "%ld" to display size_t
values), so the only thing I can think of is that your RHIDE or DJGPP
configuration is messed up somehow.  Can you compile these programs from
MS-DOS?  If so, what does gcc report?
