Ha! I should have been able to figure out nproc. :-)

Thanks again for a quick turnaround here. Unfortunately, I still get build errors from parallel make. From an excerpted build log:

It builds if I remove -j from the make invocation entirely in PKGBUILD, however.

Typo, my bad, it should be "nproc". Fixed.

@aksr: That seems to have mostly done it. I did get some odd, seemingly non-deterministic build errors; part of that might be the -j$(proc) argument to make, however. proc doesn't seem to be installed on my machine (and I'm not sure what package it comes from), but if I stopped that argument from the make invocation in PKGBUILD it built fine.

Thanks for the quick turn around!

@dancrossnyc: Try now.

Sadly, icon has stopped building recently, apparently due to an prototype incompatibility: some comparison functions appear to take no arguments in their prototypes, which recent compilers interpret as "void", causing build errors. E.g.,

rttdb.c: In function ‘dumpdb’:
rttdb.c:286:57: error: passing argument 6 of ‘prt_impls’ from incompatible pointer type [-Wincompatible-pointer-types]
  286 |    prt_impls(db, "functions", bhash, num_fnc, sort_ary, name_cmp);

or,

I am not at my Arch Box right now, sorry. aksr, feel free to update.

The university admins broke all links once again. The tarball for 9.5.1 is now found at https://www2.cs.arizona.edu/icon/ftp/historic/v951.tgz, but there are newer releases available on the official GitHub page, https://github.com/gtownsend/icon.

I see the "upstream" url was fixed the "source" url still uses the old https://www.cs.arizona.edu/... instead of https://www2.cs.arizona.edu/...

It seems that the upstream url has moved, it worked by changing http://www.cs.arizona.edu/icon/ to http://www2.cs.arizona.edu/icon/

This is missing libxt as a depends. Without libxt the build fails due to a missing /usr/include/X11/Intrinsic.h.
