Dear Peter, Michael,
Sorry for reviving the old thread. While trying to build postgres on msys2 by
meson,
I faced the same warning. The OS is Windows 10.
```
$ ninja
[2378/2402] Compiling C object
src/interfaces/ecpg/test/sql/sqlda.exe.p/meson-generated_.._sqlda.c.obj
../postgres/src/interfaces/ecpg/test/sql/sqlda.pgc: In function 'dump_sqlda':
../postgres/src/interfaces/ecpg/test/sql/sqlda.pgc:45:33: warning: format '%d'

long int
```
Before building, I did below steps:
1. Installed required software listed in [1].
2. ran `meson setup -Dcassert=true -Ddebug=true /path/to/builddir`
3. moved to /path/to/builddir
4. ran `ninja`
5. got above warning
Attached file summarize the result of meson command, which was output at the
end of it.
Also, belows show the version of meson/ninja.
```
$ ninja --version
1.11.1
$ meson -v
1.2.3
```
I was quite not sure the windows build, but I could see that gcc compiler was
used here. Does it mean that the compiler might not like the format string
"%I64d"?
I modified like below and could be compiled without warnings.
```
