msdos build patch

[Glenn Morris]

Hi,

Does this patch (or something like it) look ok for the msdos build?
The motivation is to remove the last use of cpp in lib-src/Makefile.in.

(Sorry, Gnus complains about non-printable characters, so the
config.bat patch may have mangled line-endings.)

BTW, config.bat still seems to contain code for the
no-longer-supported DJGPP v1.x case.
