I have recently tried to write a parser using bison and flex.  It
worked fine on a single input file, but I wanted to read mulitple
files and parse them in the same way.  The program always aborted from
the parser on the second file saying that EOF had been reached.  I
tried setting yyin to a new file pointer before calling yyparse but it
did not help.  Eventually I changed the skeleton file to remove the
'static' definitions from the function 'yyrestart'.  Now from the
routine which calls yyparse, I set yyin to stdin (so yyrestart won't
try to close some other file), then call yyrestart with a pointer to
the file I want to read.  This has the desired effect, but now the
line number counting I have put in the .l file is off by the number of
lines in the previous file.   Is there a correct way to read multiple
input files with one parser run?
