zsh bug

["Arnon Kanfi" <arnon@microtal.com>]

Hi,

I have discovered a bug in zsh 3.1.4 when used on SunOs. when doing an "su"
zsh will not read any of the global RC files. After tracking the problem I
have found out that su on SunOs 4.1.4 sets argv[0] to "-su" which causes zsh
to do "sh" emulation and not read the RC files. Enclosed is a small patch
that fixes the problem on SunOs (I use the "SHELL" env variable which is set
correctly to /usr/bin/zsh)

In addition to that I ran into another problem on AIX 4.3 with EGCS. Were
the
generated executable could not be loaded because of alignment problems, See
below:

      0509-036 Cannot load program ./zsh because of the following errors:
      0509-029 Alignment of text does not match required alignment.
      0509-025 The ./zsh file is not executable or not in correct XCOFF
format.
      0509-026 System error: Cannot run a file that does not have a valid
form

Adding -H512 to the linker flags in the gcc specs file fixed the above
problem.

Hope that helps.
Arnon
