Subject: Implement workaround for flex --header-file option
X-Git-Url: http://gitweb.hugovil.com/?a=commitdiff_plain;ds=inline;p=emu8051.git

Implement workaround for flex --header-file option

This is fixed in automake 1.12 and later.

The problem is that the ylwrap helper script creates a temporary directory
when running flex. Flex then correctly creates the scanner.h file inside this
temporary directory, but ylwrap does not copy it back to the build dir.
