I believe you found a small bug in McStas. To fix it, make the following
two changes:

Line 278 in file instrument.l reads

  static int parse_restricted = FALSE;

remove the sord 'static' so that it reads

  int parse_restricted = FALSE;

Line 2088 in file lex.yy.c similarly reads

  static int parse_restricted = FALSE;

change it as before to read

  int parse_restricted = FALSE;

Depending on your setup, making either just the first or just the second
of these changes may be sufficient. However, if you change first
'instrument.l' and then 'lex.yy.c' you should be safe.

Anyway, try it and let me know if it fixes the problem or not.

 - Kristian.
