just now found bug in Makefile:
....
ARCH=$(shell arch)
CFLAGS_alpha =
CFLAGS_i386  = -pipe -O2 -Wall -Wpointer-arith -Wnested-externs
CFLAGS_i486  = $(CFLAGS_i386) -m486 -fomit-frame-pointer
CFLAGS_i586  = $(CFLAGS_i486) -fno-strength-reduce -malign-loops=2
-malign-jumps=2 -malign-functions=2
LDFLAGS_alpha =
LDFLAGS_i386  =
LDFLAGS_i486  = $(LDFLAGS_i386)
LDFLAGS_i586  = $(LDFLAGS_i386)

next lines must be added(because many, and I ;-), have P2/P3 proccessors):
CFLAGS_i686  = $(CFLAGS_i586)
LDFLAGS_i686  = $(LDFLAGS_i386)

after this patch all compiles fine.

thanks to all.

wbr, Serge.
