clang does not support 16-bit assembly:

$ echo '.code16;.text;addr32 pushw 4(%esp)' | x86_64-pc-linux-gnu-gcc -c -x assembler -o dummy.o - >/dev/null 2>&1 && echo ok

    app-emulation/dosemu: fail in pkg_pretend() on clang
    
    dosemu needs 16-bit code assembly support from assembler.
    gcc/gas provides it, llvm/clang does not.
    
    Fail at pkg_pretend() for now.

Comment 6 Arfrever Frehtes Taifersar Arahesis 2020-06-24 07:46:59 UTC
It may be true that Clang does not support 16-bit assembly, but `as` is still called:

configure.ac:

if ! echo '.code16;.text;addr32 pushw 4(%esp)' | as -o dummy.o >/dev/null 2>&1; then
  echo ''
  echo '*** error:'
  echo '*** Your system has no complete code16 functional gas,'
  echo '*** you must upgrade to at least binutils-2.9.5'
  echo '*** in order to compile DOSEMU ... giving up'
  echo ''
  exit 1
fi
Comment 7 Arfrever Frehtes Taifersar Arahesis 2020-06-24 07:49:25 UTC
Actually I found that there is a patch (dosemu-1.4.1_pre20130107-as.patch) which fixes this.

dosemu-1.4.1_pre20130107-as.patch was added almost a month back. It's not clear if the patch does not apply to you or you have a stale ::gentoo tree locally.
