Bug reference: 16941
Logged by: Bryan Staley
Email address: bryan.w.staley@gmail.com
PostgreSQL version: 13.1
Operating system: RHEL 7
Description:

The following doesn't compile via ecpg

```
EXEC SQL BEGIN DECLARE SECTION;
static const char[2] TEST = "F";
EXEC SQL END DECLARE SECTION;
```

Fails with
error: invalid conversion from 'const void*' to 'void*'

This would not even compile:

$ cc -v
FreeBSD clang version 11.0.0 (git@github.com:llvm/llvm-project.git llvmorg-11.0.0-0-g176249bd673)
Target: x86_64-unknown-freebsd13.0
Thread model: posix
InstalledDir: /usr/bin

$ cat c.c

static const char[2]1 error generated. TEST = "F";

$ cc c.c
c.c:2:26: error: brackets are not allowed here; to declare an array, place the brackets after the identifier
static const char[2]1 error generated. TEST = "F";
~~~ ^
[2]: 1 error generated.
1 error generated.

My bad...

Try

EXEC SQL BEGIN DECLARE SECTION;
static const char TEST[2] = "F";
EXEC SQL END DECLARE SECTION;
