Jens,

I built against fio-de26b82 and now lex its disable by default. Tha'ts OK (cf full output below).
Concerning error with --enable-lex, i think is due that option '-o' is not valid so lex doon't generate the file leyx.yy.c => don't find it after.

MTD no
0: Warning: 1285-300 The o flag is not valid.
0: Error: 1285-331 Cannot read input file lex.yy.c
lex/yacc for arithmetic yes

If i read configure:
+1505
+1506 # Check if lex fails using -o
+1507 if test "$arith" = "yes" ; then
+1508 $LEX -o lex.yy.c exp/expression-parser.l 2> /dev/null
+1509 if test "$?" = "0" ; then
+1510 lex_use_o="yes"
+1511 else
+1512 lex_use_o="no"
+1513 fi
+1514 fi
+1515
+1516 echo "lex/yacc for arithmetic $arith"
Could you update test condition, if OS is AIX to use "less exp/expression-parser.l" and other case "-o lex.yy.c exp/expression-parser.l"
# lex exp/expression-parser.l; echo $?;ls -l lex.yy.c
