 I've worked on this today, because this test suite entry fails for
 powerpc-linux too.
 
 Unfortunately, after half a day of fiddling, I'm not sure if the reason
 this fails on HPPA is the same as the reason it fails on POWERPC.
 
 On the latter, even the following is incorrect:
 
       INTEGER*1 I
       I = -9
       PRINT*,I
       END
 
 which prints 247 ;-)
 
 So I thought, this must be a signed/unsigned "char" problem, no ?
 
 Well, AFAICS, the PA port is default-signed-char platform, so this
 analysis doesn't apply.
 
 Welllllll, perhaps this means that this afternoon multiplied one problem
 into two :-(
