PROBLEM:  (78638) (PATCH ID: OSF440-365)
********


This patch extends the maximum length of an identifier from the current
limit of 1024 characters to a new maximum length of 16 * 1024. Identifiers
longer than 1024 characters are rare, but they do occur when assembler source
files are generated by a source code generator.  Before this change, an
identifer that exceeded 1024 characters in length would result in an
assembly-time error stating that the "line is too long".
