LibSpiro, version 20240902 (1.4.0)

Libspiro is a shareable library that can be used by programs to do the Spiro computations for you.

Main improvement of interest in this release is:

• Removed bug introduced during 20221101 which caused libspiro to exit early without results. This was seen in Fontforge as straight lines (closes issue (see bug). Please update to this 20240902 release if you are running libspiro 20221101 due to this bug.

Other updates:

• Updated configure.ac to also display $libdir since 64bit needs to run './configure --prefix=/usr --libdir=/usr/lib64' for distro installs (32bit ./configure --prefix=/usr' is enough). Updated ./configure for PRE_REQ(2.70) as 2.64 was already showing warnings and problems of obsolete macros for latest versions of linux.
• Removed config.guess and config.sub since these files go stale with time and you may have more up to date versions inserted when you run 'autoreconf -i; automake'.

Users unable to run autotools can fetch the dist tar file included here, which can run from ./configure (without needing to run autoreconf -i; automake; first).
