[PATCH 13/26] serial_write: change prototype to take a void-pointer buffer.

[Pedro Alves]

Eli, this patch touches ser-go32.c.  Is it OK?

Most recent version here:

 http://sourceware.org/ml/gdb-patches/2013-04/msg00364.html

I've now installed a cross djgpp toolchain (gcc 4.7.2) on my Fedora 17
machine (*), and verified this causes no build regressions.  I stumbled
on a couple unrelated preexisting issues I had to hack around, but GDB
built.  Moreover, djgpp is -Wpointer-sign clean too with the whole
series applied.
