Hello,

as promised, here is the patch for the regressions introduced by my 
change at revision 162776.

Nothing special, modified symbols have to be committed in non-parsing 
mode. And one needs to call gfc_undo_symbols (maybe through 
reject_statement) in case one emits an error.

Thanks to Janus for taking part to the regression hunt.

Regression testing in progress on x86_64-unknown-freebsd8.0, and patch 
was reported regression-free by Dominique in the PR.

OK for trunk/4.5 (I plan to backport the other PR42051 fixes too) ?

Mikael
