I'm cross compiling for the x86_64-w64-mingw32 and i686-w64-mingw32 hosts only the gdb server (USE="lzma multitarget server"). In both cases it fails with the above error. Apparently building gdb requires dev-util/source-highlight even when the source-highlight USE flag is not enabled.
'checking for the source-highlight library... yes' probably found host's source-highlight library. I think there are 3 issues here: 1. USE=-client should not try to pull in source-highlight 2. BUILD's toolchain was used to detect source-highlight, not HOST's 3. USE=-source-highlight had no effect Let's see if [2.] or [3.] can be easily addressed. Meanwhile the workaround can be to pass EXTRA_ECONF=--disable-source-highlight explictly: # EXTRA_ECONF=--disable-source-highlight x86_64-w64-mingw32-emerge -v1 gdb

That is never correct as client is supposed to be running on CHOST. The change switches to CHOST's PKG_CONFIG.

We started building gdb out-ouf-tree as this release has a limitation of not supporting build tree. But migration of out-of-tree build broke the sace of USE="server -client": gdb-9999:src_configure() (ok): if use server && ! use client ; then cd gdb/gdbserver fi econf gdb-9.1:src_configure() (bad): if use server && ! use client ; then cd gdb/gdbserver fi pushd "${GDB_BUILD_DIR}" || die ECONF_SOURCE=${S} econf popd Note: we lost 'cd gdb/gdbserver' effect completely.

Let's rely on [2.] alone. Next gdb release should clean it up.
