compiler warnings

[Tim Waugh]

When compiling bash with GCC there are a number of alarming-looking
warnings, and several of them could be avoided by minor changes to the
code.  For example:

bashline.c:2976: warning: suggest parentheses around assignment used
as truth value

  for (passc = 0; c = string[i]; i++)

This could more readably be written:

  for (passc = 0; (c = string[i]) != '\0'; i++)

Would you be willing to accept patches to make changes such as this?

Thanks,
Tim.
