HP-UX hostname B.11.00 E 9000/785 2006047808 8-user license
cpp.ansi: HP92453-01 A.11.01.20 HP C Preprocessor (ANSI)
ccom: HP92453-01 A.11.01.21505.GP HP C Compiler
The code for HAVE_PTHREAD_SERIALIZED_ACCEPT is not portable to HPUX11 because there is no
/dev/zero. But on HPUX it is possible to map pages anonymous as shown below. I run a server
on the hardware described in the Environment window and it looks fine.
To run the server with PTHREAD_SERIALIZED_ACCEPT the ap_config.h file has to be changed.

Kind regards
