yacc under cygwin - undefined symbols

[Christoph Kukulies]

Compilation (make, yacc, lex) of little parser used to work fine under
BSD (FreeBSD) and now that I want to build it under cygwin, I suddenly
get

gcc -c y.tab.c
y.y: In function `yyparse':
y.y:17: error: `lfd' undeclared (first use in this function)
y.y:17: error: (Each undeclared identifier is reported only once

lfd is a static variable which is defined at the end of the .y file,
instead at the beginning. That is, the yyparse main program is appended
at the end instead at the beginning of the generated y.tab.c.

Strange. How can I influence this?

lex and yacc are offtopic in CLC,. you probably need to ask in a linux
or unix programming group, or a general programming one.

By reading the yacc documentation, Googling, or posting in a more
appropriate newsgroup (perhaps comp.unix.programmer, comp.compilers,
or gnu.utils.help). You don't really have a C question; you have a
yacc question.
