The configure script will warn that "make indent" is unavailable, but
apart from that this input is not actually used for the build process.
* gnu/packages/flex.scm (flex)[inputs]: Remove INDENT.
* gnu/packages/commencement.scm (flex-boot0)[inputs]: Likewise.
This is a followup to b1593c1c4f.
* gnu/packages/flex.scm (flex)[inputs](bison-for-tests): Use
'substitute-keyword-arguments' instead of overriding them altogether.
This ensures that #:parallel-build? and #:parallel-tests? are
preserved.
This reverts commit 77e2538eda and fetches the
gzip-compressed tarball. We do this so that flex-boot0 will not require lzip.
* gnu/packages/flex.scm (flex)[source]: Fetch the '.tar.gz' tarball.
[native-inputs]: Remove lzip.
* gnu/packages/bison.scm (bison): Move FLEX to 'inputs', and remove the
hack that turned off its test suite.
* gnu/packages/flex.scm (flex): Add 'bison-for-tests' in 'inputs', and
use that to run the tests.
* gnu/packages/bison.scm (bison): Update to 3.0. Make Perl a native
input. Add a variant of Flex as a native input. Use #:export instead
of 'define-public'.
* gnu/packages/flex.scm (flex): Use #:export instead of 'define-public'.
