- Subject: [patch/committed] Remove dec-C compiler warnings (VMS)
Hi,
dec-C (the native VMS compiler) doesn't like arithmetic on void * (a gcc extension), and also
detect an alias violation. This patch remove the first issue and turn the second warning into
an informational message. (The issue is that object files are marked as generated with warnings,
which is not very elegant).
Committed on trunk.
Tristan.

* makefile.vms (CFLAGS): Make badalias warnings informational.
* vms-lib.c (vms_lib_bread): Avoid arithmetic on void pointer.
