Hi Daniel,

your commit c25383ae "rename "easy" statemachines: call them block
instead" seems to have broken compilation with old GCC and -Werror due
to a conflict between parameter "wait" of the new Curl_pp_statemach()
and system-provided function wait(2).

This was on a quite old and dirty machine when I accidentally used the
ancient, platform-provided GCC 3.4.6, but still I thought I'd better
let you know as you seem to care even about such systems around here.

gcc -DHAVE_CONFIG_H -I../include/curl -I../include -I../include
-I../lib -I../lib -DCURL_HIDDEN_SYMBOLS -DDEBUGBUILD -DCURLDEBUG
-fvisibility=hidden -g -O0 -pedantic -Wall -W -Wpointer-arith
-Wwrite-strings -Wunused -Wshadow -Winline -Wnested-externs
-Wmissing-declarations -Wmissing-prototypes -Wno-long-long
-Wfloat-equal -Wno-multichar -Wsign-compare -Wundef
-Wno-format-nonliteral -Wendif-labels -Wstrict-prototypes

No other problems with GCC 4.6.2 on the same machine, or when I
changed it to e.g. "bool waitx".

Kind regards,
Jiri
