* shlib-versions [USE_IN_LIBIO] (.*-.*-gnu-gnu*): Set earliest
supported version for libc 0.2.90.libio to GLIBC_2.2. * Makeconfig (soversions.mk): Grok new third column in shlib-versions, and use it to emit new variable `map-firstversions'. * scripts/firstversions.awk: New file. * Makerules (Versions.all): Use scripts/firstversions.awk and the $(map-firstversions) value to generate a modified versions list that includes renames in "A = B" syntax for each version set earlier than the "earliest symbol version" named in shlib-versions. * scripts/versions.awk: Recognize "A = B" lines in the input to mean rename version set A to B in the output to the intermediate file. * scripts/abi-versions.awk: New file. * Makerules (abi-versions.h): New target, generated by that script. [$(versioning) = yes] (before-compile): Prepend abi-versions.h. * include/shlib-compat.h: New file, uses that generated header.
