Change to emacs.c: USAGE1 string is too big for Microsoft compiler.

Change to emacs.c: USAGE1 string is too big for Microsoft compiler.

[Stephen Powell]

The latest update to emacs.c makes the USAGE1 string to long for
Microsofts compiler.  It doesn't like this line:

      printf (USAGE1, argv[0]);

`----

According to Microsofts site
<http://msdn.microsoft.com/library/default.asp?url=/library/en-us/vccore/html/C2026.asp>

The string was longer than the limit of 2048 single-byte characters.

Prior to adjacent strings being concatenated, a string cannot be
longer than 2048 single-byte characters.

A Unicode string of about one half this length would also generate
this error.

Stupid compiler.

Please try "cvs up", I installed a change that should fix this.

And thanks for the report.

For what it's worth, a mere 509 chars is apparently the limit for c89,
according to gcc -pedantic.

It is just the minimum very implementation must be able to handle,
C99 has 4095 characters (so Microsoft does not comply?).
C99 also says, "Implementations should avoid imposing fixed
translation limits whenever possible".

The previous length was close to 2096, so it seems that msvc is the
closest to this limit that we have encountered in practice. I presume
it is just a warning from gcc -pedantic?
