[Aldor-l] patch: obsolete POSIX name for CLOCKS_PER_SEC

[Bill Page]

Laurentiu,

Here is perhaps the first user contributed patch for the
soon-to-be-released version of Open Source Aldor:

On openSuSE Linux 10.2 apparently the old POSIX name for the clock
ticks per second constant is no longer supported in the standard
system header files. As a result the build of the compiler fails early
in the process with the name HZ undefined.

The following patch defines the necessary constant in terms of another
header file.

--------

I have successfully built Aldor with this change on openSuSE 10.2. I
think this patch should not cause problems on other systems where the
old name is still used but I have not tested it on any other systems.
If you agree the patch is ok, I can check it in to CVS.

Note: I have just updated 'README.developers' in CVS to mention
Berkeley Yacc as a dependency as agreed during the workshop on
Thursday.

Regards,
Bill Page.
