Microsoft. Microsoft still owns submarine patents on exFAT. We
old-timers have been down that road before. It is true Microsoft
published the specification in 2019 and SDXC flash device organization
standardizes on it.
AFAIK exFAT is now free to open source implementations, but I have
not taken a lawyer advice. I leave it to the OpenIndiana community
to decide whether there is a place for exFAT in its ecosystem.
I have no personal interest in it, I ported this exFAT implementation
only because I had to reboot on Windows to play a presentation by a
colleague on a USB key. A real-life situation.

It would be better to support FAT+ draft 2. (See Wikipedia on FAT ref.
34). FAT+ simply uses 38 bits for file size so up to 256 GiB is
supported. The existing PCFS should be modified to at least be FAT+
aware. DR-DOS and FDOS support FAT+.
Neither exFAT nor FAT+ provide journaling. Microsoft's patents expired
on FAT32 and VFAT Long File Names. That is why exFAT 64 bit file size
support now exists. Just a useless waste of resources.

I have been trying to package for OpenIndiana a driver and utilities

The packaging went fine locally (by gmake publish), but the pull
request check fails on :
aclocal: error: aclocal: file '/usr/share/aclocal/wxwin.m4' does not
exist
(see https://github.com/OpenIndiana/oi-userland/pull/7389)
I have no idea of what triggers this, and as this does not occur
locally, I cannot make my own tries. I suspect having a difference of
versions in my autotools (fully updated). I also suspected the use of
the deprecated macro AC_PROG_CC_C99 had something do do with that,
but removing it does not bring any change.
I am at a loss over what else I could try, so I am giving up until
somebody points me at what I am doing wrong.
