Tried to build gcc-4.3-20071123 for DJGPP (native build). Run into a following
libiberty related
problem problem:
vasprintf() was not found when building gcc stage 1.
vasprintf() should be provided by libiberty as DJGPP does not have own.
Inspecting libiberty
Makefile and present object files however showed that none of procedures that
are missing in DJGPP
were included in built libiberty.a:
LIBOBJS =
For GCC-4.2.2 I had in libiberty Makefile:
LIBOBJS = ${LIBOBJDIR}./asprintf$U.o ${LIBOBJDIR}./mempcpy$U.o
${LIBOBJDIR}./mkstemps$U.o
${LIBOBJDIR}./sigsetmask$U.o ${LIBOBJDIR}./strndup$U.o
${LIBOBJDIR}./strverscmp$U.o
${LIBOBJDIR}./vasprintf$U.o
and as result no such problem.
As the difference between Makefile.ac versions contains DJGPP related stuff not
from me (see
attachment) , I'm sending this message at first to DJGPP related list
