ltmain.sh "integer expression" errors.

[Rob Browning]

FWIW I added 

  max_cmd_len=128

to the top of my ltmain.sh here and re-config/built and the errors
went away.  This might help those having trouble.  Just make sure you
pick a value your system can handle....I guessed, though I'm sure
there's some call or header that'll tell you.
