Subject: dtc: Use a custom name for lexer output
Date: Wed, 26 Sep 2007 14:05:54 +1000 [thread overview]
Message-ID: <20070926040554.GA32097@localhost.localdomain> (raw)
This patch makes dtc use the name dtc-lexer.lex.c for the flex output,
instead of the default lex.yy.c. If nothing else that makes the
filename more obvious when/if dtc is embedded into other projects.
It also explicitly requests flex as the lexer generator, rather than
using make's default $(LEX).
