+ 
+ In the above function uniquepipe() of popen.c, the format for the pipe 
+ name ("pipe%05d.tmp") will generate an invalid file name for DOS. In 
+ the DOS FAT file system, the base filename can only be 8 characters 
+ (with a maximum file name extension of 3 characters), anything greater 
+ than this will be silently truncated by DOS. Thus, pipe00000.tmp is 9.3, 
+ where the DOS max is 8.3, so isn't there a problem where pipe00001 and 
+ pipe00002 will get confused? 
+ 
+ How about %04d instead. I would think that making the assumption that 
+ this implementation of pipes for DOS will only have 9999 pipes at any
+ given point in time would be better than losing the rightmost digit
+ in the current implementation.
+ 
+ (this bug is now fixed)
