Re: autoconf 2.50 generated configure script on os/390

[Akim Demaille]

| Hi,
| during installation of the newer alpha versions of VIM 6 on an os/390 unix
| machine, I noticed that autoconf 2.5 produced a configure script that would
| not run under os/390 unix. Bram Moolenaar switched from autoconf 2.13 to
| autoconf 2.5 from his VIM 6.0 alpha H to alpha I. Alpha I and beyond can
| not be configured on os/390 without either modifying the configure script
| or letting autoconf 2.13 generate a new one from configure.in
| The manual changes required in configure were:
|    a signal #13 was traped -> not supported on OS/390 -> removed
|    a file descriptor #6 was created -> not supported on OS/390 -> removed
|    I received some permission warnings with the last 2 MV commands, but I
|    am unsure what those mean. The command executed though. -> replaced with
|    CP commands
| 
| The configure file that autoconf 2.13 generated ran fine without any
| changes.
| 
| I believe a change to autoconf 2.50 (or 2.51?) to re-establish support for
| the os/390 platform would be a good thing.

Sure, but could you send patches?  What FD should we use?  Why can't
we use 6?

Without any further information, we won't be able fix anything.
