I receive:

ERROR 003: Parser error - syntax error, unexpected LCASEFIRST_IDENT_SYM, expecting RIGHT_BRACE_SYM in line 1395

when compiling Allied Telesis mib file:

http://www.oidview.com/mibs/207/ALLIEDTELESYN-MIB.html

File extension is .mib not .txt, I renamed .txt.
Follow near 1395 line (when read with Ultra Edit line 1395 start at first ccCliListEntry after "SYNTAX  SEQUENCE OF"... strange !!! ):
