Subject: [PATCH] undefined reference yywrap in winhlp32/macro.lex.yy.c
 (flex-2.6.3)

flex-2.6.3 uses C preprocessor macros to change the prefix of its functions
from the standard yy to a user-defined one. This is a change in Flex behavior
and causes wine to fail with any version of Flex newer than 2.6.1.

The failure is caused because programs/winhlp32/macros.lex.l only defines the
yywrap macro if it is not already defined. The end result is C code that is
looking for an undefined yywrap() function.

I have attached a patch that fixes this issue by removing the yywrap macro check and definition from macros.lex.l and adding the noyywrap flex option.
