* use relative paths in ldscript.ld and crt0_includes.h * avoid use of dd(1) in xcompile * build libregex for kconfig, if necessary * work around missing utsname on win32 * unlink targets before rename on win32 * implement (crude) mkstemp for win32 * avoid open/read/close, use fopen/fread/fclose instead * don't free certain data structures in romcc on win32 to avoid crashes (likely use-after-free()) * handle "\CRLF" and win32 style absolute paths (X:/ or X:\) in romcc * make lzma (part of cbfstool) build on XP * implement ntohl/htonl on win32 * handle CRLF in awk script * set larger stack for romcc on win32 Signed-off-by: Patrick Georgi <patrick.georgi@coresystems.de> Acked-by: Peter Stuge <peter@stuge.se> git-svn-id: svn://svn.coreboot.org/coreboot/trunk@4952 2b7e53f0-3cfb-0310-b3e9-8179ed1497e1
