[short answer, it works in that src/Makefile is now valid]

Here's what I get now (using a snapshot from about 12 hours ago):

gcc -D_BSD_SOURCE  -DHAVE_CONFIG_H    -I. -I../src -I/mirror/d/emacs/lib-src -I/mirror/d/emacs/lib-src/../src -L/usr/X11R6/lib -D_BSD_SOURCE   -g -O2  /mirror/d/emacs/lib-src/emacsserver.c -lc -o emacsserver
/mirror/d/emacs/lib-src/emacsserver.c: In function `main':

Here's emacsserver.i.gz:

emacsserver.i.gz

But if I actually `cd src' and run make from there, it does indeed work.

I'll file a report for the original problem later,
assuming no one else beats me to it.
