Hello!

I've got a VxWorks IOC that stops executing st.cmd as follows when it
tries loading the .munch file:

---8<---
cd topbin
value = 0 = 0x0
load("17lab.munch")
Undefined symbol: snprintf (binding 1 type 0)
ld error: Module contains undefined symbol(s) and may be unusable.
value = 0 = 0x0

Done executing startup script /ioc/boot/17lab/st.cmd
17lab>
--->8---

Does anyone know what's wrong or how to debug this?

I've tried running nmppc on 17lab.munch, but there are *many* symbols
prefixed with a 'U'.  In fact, when I run nmppc on a known-good .munch
file, it too shows many symbols prefixed with a 'U', so I'm not
confident I'm looking at the right thing.

Environment:
* VME processor module: Motorola MVME-2100 (vxWorks-ppc603)
  - CPU: MPC 8240
  - Memory: 32 MB
* OS: VxWorks 5.5.2
* Kernel: WIND 2.6
* BSP: mv2100-anj-fix-boot-hang (by Andrew Johnson)
* Build toolchain: Tornado 2.2.2
* EPICS 3.14.12.5 (+ Known Problems patches)
* synApps 5.8 (+ various module upgrades)

Thank you!

Lewis
