Unfortunately, this already happens during the build process...

Environments:
DEC C V5.7-004 on OpenVMS VAX V6.2
DEC C V5.7-004 on OpenVMS Alpha V6.2-1H3
On the VAX, $ @configure "-des" bombs out with
First let's make sure your kit is complete. Checking...
Some of the files not found include:
[-.os2]diff.configure
(not VMS fault) After removing that file from MANIFEST, it "Looks
good...".
I suppose that'd happen on Alpha too.
Next on VAX: the call to 'gcc_symbol' isn't framed by SET NOON / SET ON,
and
so bombs out. Same on Alpha, I'd suppose.
Then, configure.com runs right through to the end on VAX and Alpha.
MMS, however, stops on VAX at:
CC/DECC
/Include=[]/Standard=Relaxed_ANSI/Prefix=All/Obj=MINIPERLMAIN.obj/NoList
/Define=PERL_CORE MINIPERLMAIN.C
typedef unsigned off_t;

prior
declaration in this scope at line 308 in UNISTD.
At line number 10 in SYS$COMMON:[SYSLIB]STAT.H;1.
}
On Alpha, it runs through to building POSIX, and bombs with

So much so far. I guess my DEC C needs updating.
Unfortunately, I don't have too much time on my hands to really get
involved.
