tccgen.c: doubles need to be aligned, on ARM. The section_reserve() in init_putv does not do that. -D ONE_SOURCE: is now the default and not longer needed. Also, tcc.h now sets the default native target. These both make compiling tcc simple as "gcc tcc.c -o tcc -ldl" again. arm-asm.c: enable pseudo asm also for inline asm tests/tests2/Makefile: disable bitfield tests except on windows and x86_64 and don't generate-always tcc.c: fix a loop with -dt on errors configure: print compiler version (as recognized) tccpp.c: actually define symbols for tcc -dt clear static variables (needed for -dt or libtcc usage) 96_nodata_wanted.c: use __label__ instead of asm lib/files: use native symbols (__i386__ etc.) instead of TCC_TARGET_...
