Pass move-if-change to awk. (common-generated): Add $(version-maps) and sysd-versions. * versions.awk: Moved to... * scripts/versions.awk: ... here. Use move-if-change to void touching unchanged files. Print "version-maps = ..." instead of "all-version-maps = ..." and without $(common-objpfx). Explain expected variable names. * Makefile (distribute): Updated. 1998-07-06 Andreas Schwab <schwab@issan.informatik.uni-dortmund.de> * misc/getttyent.c (getttyent): Don't return with locked stream. * misc/mntent_r.c (__getmntent_r): Likewise. 1998-07-07 18:24 Ulrich Drepper <drepper@cygnus.com> * libio/fileops.c (_IO_do_write): Don't shrink wwrite buffer to zero if stream is line buffered.
