Here's another compilation problem that's shadowed by having a system-installed
curl on the compilation machine. A build on an AIX box without curl installed
tripped this. Symptom:

xlc -DHAVE_CONFIG_H -I. -I../../../curl/tests/server -I../../lib -I../../src -I../../../curl/lib -DCURLDEBUG -g -g -c ../../../curl/tests/server/sws.c
"../../../curl/lib/setup.h", line 142.10: 1506-296 (S) #include file <curl/stdcheaders.h> not found.
make[2]: *** [sws.o] Error 1
make[2]: Leaving directory `/users/tor/curl-build/build-23376/tests/server'

Fix follows below.
