Java front-end on m68k-next-nextstep3: parse.y:3980: parse errorbefore `DIR'

[Toon Moene <toon at moene dot indiv dot nluug dot nl>]

Hi,

Here's the scoop:

/nfs/hoser/beer/java/egcs/gcc/java/parse.y: In function  
`read_import_entry':
/nfs/hoser/beer/java/egcs/gcc/java/parse.y:3980: parse error before `DIR'
/nfs/hoser/beer/java/egcs/gcc/java/parse.y:3979: warning: type of

And - of course - my build (LANGUAGES="c f77") still fails on:

It's beyond me why a move from a QImode memory location to an  
SImode register would cause any problems on the m68k ... but perhaps  
someone in the know could point it out to me ...

Cheers,
