Aug 31, 1998:
The interface to HANDLE_PRAGMA has changed. It now takes three arguments.
The first two are pointers to functions that should be used to read characters
from the input stream, and to push them back into the input stream respectively.
The third argument is a pointer to a null terminate string which is the first
word after #pragma. The expression supplied by HANDLE_PRAGMA should return
- non-zero if it parsed and implemented the pragma. Otherwise it should return
+ nonzero if it parsed and implemented the pragma. Otherwise it should return
zero, and leave the input stream as it was before the expression was evaluated.
A new back-end definable macro has been added: INSERT_ATTRIBUTES. This macro
In an effort to decrease cache thrashing and useless loads we've changed the
third argument to the DEFTREECODE macro to be a single char. This will
- effect languages that defined their own tree codes (usually in a .def file).
