lynx-dev VARARGS and HTSprintf

[pg]

I didn't pay enough attention to the varargs discussion in
the last couple days.  dev.6 breaks on OS/390 with:

Library/Implementation/HTString.c
ERROR CBC3343 ./../../../../WWW/Library/Implementation/HTString.c:549
    Redeclaration of HTSprintf differs from previous declaration
    on line 57 of "../../../../WWW/Library/Implementation/HTString.h".
ERROR CBC3343 ./../../../../WWW/Library/Implementation/HTString.c:580
    Redeclaration of HTSprintf0 differs from previous declaration on
    line 59 of "../../../../WWW/Library/Implementation/HTString.h".
FSUM3065 The COMPILE step ended with return code 12.

I believe OS/390 is a pathological situation; ANSI_VARARGS is defined,
but a compiler bug (fixed in Next Release, I hope) forces me to run
with __STDC__ undefined.  This sends me down a truly bizarre path.

So, the attached patch may not be suitable for everyone; in fact,
it may be suitable for no one but me.  I merely offer that it
circumvents the defect of OS/390, and seems to break nothing
additional with gcc on Solaris 2.5.

FWIW,
