Library support in gnat-4.6.3?

[Svante Signell <svante.signell@telia.com>]

Hi,

Sorry to bother you but when building gnat-4.6.2-3 building of libraries
was supported. However, when building gnat-4.6.3-2 with the previous
version library support was disabled. Where it that setting controlled?

The configuration for GNU/Hurd was approximately the same:
ifeq ($(strip $(filter-out %86 gnu%,$(arch) $(osys))),)
  LIBGNAT_TARGET_PAIRS = \
  a-intnam.ads<a-intnam-freebsd.ads \
  a-numaux.adb<a-numaux-x86.adb \
  a-numaux.ads<a-numaux-x86.ads \
  s-inmaop.adb<s-inmaop-posix.adb \
  s-intman.adb<s-intman-posix.adb \
  s-osinte.adb<s-osinte-kfreebsd-gnu.adb \
  s-osinte.ads<s-osinte-kfreebsd-gnu.ads \
  s-osprim.adb<s-osprim-posix.adb \
  s-taprop.adb<s-taprop-posix.adb \
  s-taspri.ads<s-taspri-posix-noaltstack.ads \
  s-tpopsp.adb<s-tpopsp-posix-foreign.adb \
  system.ads<system-freebsd-x86.ads

  TOOLS_TARGET_PAIRS =  \
    mlib-tgt-specific.adb<mlib-tgt-specific-linux.adb \
    indepsw.adb<indepsw-gnu.adb

  EH_MECHANISM=-gcc
  THREADSLIB = -lpthread
  GNATLIB_SHARED = gnatlib-shared-dual
  GMEM_LIB = gmemlib
  LIBRARY_VERSION := $(LIB_VERSION)
endif

mlib-tgt-specific-linux.adb does not specify
Library_Support but mlib-tgt.adb does??
   function Support_For_Libraries_Default return Library_Support is
   begin
      return Full;
   end Support_For_Libraries_Default;

and mlib-tgt.adb is the same in both versions!

Thanks!
