Patch 8.0.1723
Problem:    Using one item array size declaration is misleading.
Solution:   Instead of using "[1]" and actually using a larger
array, use
             "[]".  This is to verify that this C99 feature works
for all
             compilers.
Files:      src/structs.h, src/getchar.c
If you notice a prolem because of this patch, please speak up!
Also if it's just a compiler warning.  We want to know if this C99
feature works for everybody.
After this patch (8.0.1723), HP-UX throws this error:
<snip>
Starting make in the src directory.
If there are problems, cd to the src directory and run make there
    cd src && make first
    cc -c -I. -Iproto -DHAVE_CONFIG_H   -O2  -o objects/arabic.o arabic.c
cc: "structs.h", line 514: error 1578: Size of struct or union member is
unknown.
*** Error exit code 1

Stop.
*** Error exit code 1

Stop.
</snip>

It looks like HP-UX compiler doesn't like flexible arrays.
Disappointing...

This document suggests it was added at some point:
https://support.hpe.com/hpsc/doc/public/display?docId=emr_na-c02670372

Apparently it was added with version B.11.11.16.
What version are you using?
Is there any way to upgrade?

According to "uname -a" I am on:
HP-UX B.11.11 U 9000/800
The c compiler says it is:
HP C/HP-UX Version 11.11.02

Old stuff I know. The machine *might* be retired and replaced with a Red 
Hat linux box in the next 18 months or so. Maybe. In the meantime, there 
is no chance of an upgrade.

Also, after the related patch 8.0.1730, the HP-UX throws this (from 
configure):
<snip>
Starting make in the src directory.
If there are problems, cd to the src directory and run make there
   cd src && make first
   rm -f auto/config.cache
...
checking for nawk... no
checking for awk... awk
checking for strip... strip
checking for ANSI C header files... yes
checking for sys/wait.h that is POSIX.1 compatible... yes
checking if the compiler can handle Vim code... configure: error: 
compiler does not work properly - see auto/config.log
*** Error exit code 1

Stop.
*** Error exit code 1

Stop.
