* parse.y (catch_clause_parameter:): Still set `$$' to NULL_TREE
in case of error. Error message tuned.
This fixes a catch clause error handling reported on the java-discuss
mailing list:
http://sourceware.cygnus.com/ml/java-discuss/1999-q4/msg00358.html

* exception.cc: Remove prototype declarations for malloc and free.
These clash with recent versions of glibc, which specifies `throws ()'
when __cplusplus is defined. Instead, #include <stdlib.h>.
From-SVN: r30709
Fix for gcc.c-torture/noncompile/920824-1.c on SH (and mips?)
* dwarfout.c (field_byte_offset): Size can be zero if there was
an error.
