The script c89 and c99 from gcc-multilib-git doesn't work.

The PKGBUILD doesn't escape the $ correctly. It is expanded when the package is built. Here is a patch that addresses these issues.

Warning: After upgrading the Linux kernel to 5.4.2-arch1-1, nvidia failed to compile for me. The effect was that my system could still boot but refused to bring up the graphical environment.

If you are hit, I recommend to first downgrade gcc to the official Arch package:

sudo pacman -U /var/cache/pacman/pkg/gcc**9.2.0-4*

Then force a recompilation of nvidia find out which packages need to be reinstalled:

pacman -Q | grep nvidia

In my case:

sudo pacman -S lib32-nvidia-utils lib32-opencl-nvidia nvidia-dkms nvidia-utils opencl-nvidia

If you install gcc-multilib-gcc, you might run into this dependency error:

error: failed to prepare transaction (could not satisfy dependencies)
:: removing gcc breaks dependency 'gcc=8.3.0-1' required by gcc-fortran
:: removing gcc breaks dependency 'gcc=8.3.0-1' required by gcc-objc

Until there is a proper fix, it should work to install these three packages together:

gcc-multilib-git gcc-fortran-multilib-git gcc-objc-multilib-git

Please let me know if someone knows how to correctly define the dependences in the PKGBUILD. (Maybe gcc-multilib-git should automatically pull gcc-fortran-multilib-git and gcc-objc-multilib-git?)

@SpaceboyRoss Unfortunately, I cannot reproduce. Can you give some more details? And more important, can you reproduce if you remove all old state? "gcc is not a commit" could indicate that it fails to checkout the sources.

Independent of that, I noticed that this package (gcc-multilib-trunk-git) is affected by the same build issue discussed in https://aur.archlinux.org/pkgbase/gcc-git/

/home/phil/aur/gcc-multilib-trunk-git/src/gcc/gcc/config/i386/i386.c: In function ‘const char* output_fix_trunc(rtx_insn*, rtx_def**, bool)’:
/home/phil/aur/gcc-multilib-trunk-git/src/gcc/gcc/config/i386/i386.c:19200:1: error: invalid operand in unary operation

      | ^~~~~~~~~~~~~~~~

I'll try to port the workaround from gcc-git.

@tuxsavvy I have integrated your patch. Thank you!
