roll of objc-improvements-branch likely causing---

[Loren James Rittle]

Hello Ziemowit,

[...in bootstrap log...]
if bison  -o op$$.c objc-parse.y ; then \
[...]
objc-parse.y:2391.14-2394.11: type clash (`ttype' `') on default action

with bison (GNU Bison) 1.75 on i386-unknown-freebsd4.8 (no other
configuration tested).  If I understand the error message, then these
lines are of interest:

[2391:]  objc_try_stmt:
          AT_TRY
                { objc_build_try_prologue (); }
          compstmt
        ;

Memory says that bison has tightened error checking but I have not
consulted the history to understand why this is now/was flagged...

Thank you for fixing this mainline bootstrap failure ASAP.

Regards,
Loren
