Hi!
Here's an attempt to implement warning disabling by passing a `no<category>'
argument to -W (or in the WARNINGS env var. The `syntax' category is also
turned back on by default.
2000-05-11 Didier Verna <[EMAIL PROTECTED]>
* autoconf.sh (warnings): enable the `syntax' category by default,
support the `no<category>' argument to disable warnings.
* doc/autoconf.texi (Invoking autoconf): document.

treats warnings as errors.
+By default, only the `syntax' category is reported. You can disable a

The soon-do-be-standard environment variable @code{WARNINGS} is
supported: it consists in a comma separated list of categories. It is
honored iff @samp{--warnings} was not used.
