>Description:
Running configure in an empty build directory to perform a VPATH build of mysql,
I noticed that configure created on temporary and one permanent file in $srcdir.
This shouldn't happen: $srcdir should be treated as read-only (e.g. to support
building from a read-only source partition, but also to avoid interference from
several different instances of configure running in different build dirs with
the same srcdir.
The files in question are $srcdir/ac_available_languages_fragment
(AVAILABLE_LANGUAGES_ERRORS_RULES in configure/configure.in) (transient) and
strings/ctype_autoconf.c (permanent).
>How-To-Repeat:
mkdir objdir
cd objdir
<path to srcdir>/configure
>Fix:
It may suffice to replace $srcdir by $top_builddir for
AVAILABLE_LANGUAGES_ERRORS_RULES.
I'm not sure (and haven't tried yet) if a VPATH build would work if
ctype_autoconf.c were created in $builddir.
