I just got djgpp v2.01, runing on a 486DX2-66 ms-dos/win3.1
(hey it's old but paid for :) ) 

I'm trying to read a binary file by passing a struct to fread, and
everything seems ok except when there is an odd number of shorts between
longs, then it skips two bytes after reading the short, then reads the
next long. this became aparent when I compared the values of num_records
and beyond to what they should be. Any ideas ?

thanks
Siggi

	fclose(data);
