problems building a file -O0

[Manuel Bouyer <bouyer%antioche.eu.org@localhost>]

Hi,
on netbsd-4, the compiler dies when building a file in x11/Xserver/os for vax.
Compiling -O0 fixes the crash, so I tried this:

When I call mbmake-vax from the command line in this directory, it works
(-O0 is added when building connection.o, and all is well). When it's
called from build.sh, -O0 isn't added and the compiler crash.
Any idea why ? What's the difference between mbmake-vax called from
command line, and from build.sh ?
