Fails to build on RHEL-5:

         CC convert-dtsv0-lexer.lex.o
cc1: warnings being treated as errors
convert-dtsv0-lexer.lex.c:693: warning: no previous prototype for =91yyle=
x=92
make: *** [convert-dtsv0-lexer.lex.o] Error 1

Removing -Werror from the Makefile gets me a bit further:

         CC dtc-lexer.lex.o
dtc-lexer.lex.c:683: warning: no previous prototype for =91yylex=92
dtc-lexer.l: In function =91push_input_file=92:

dtc-lexer.l: In function =91pop_input_file=92:

         CC dtc-parser.tab.o

/home/buildbot/git/dtc/dtc-lexer.l:201: undefined reference to

collect2: ld returned 1 exit status
make: *** [dtc] Error 1

I guess the flex version shipped with RHEL-5 is too old.

$ rpm -qf $(which lex)
flex-2.5.4a-41.fc6

cheers,
