On platform lii6gc, the mps needs a bunch of symbols which are not defined if the -ansi option is given to gcc. these can be enabled by defining features like _gnu_source, but all headers share a common set of features (via <feature.h>) and so all sources in the same compilation unit must turn on the same set of features. make sure this happens by turning on the features in config.h (not mpstd.h).
Remove <string.h> from mpsi.h (not needed). Copied from Perforce Change: 182124 ServerID: perforce.ravenbrook.com

|

* The MPS needs the following symbols which are not defined if the
|
||||
* -ansi option is given to GCC:

*
|
||||
* Source Symbols Header Feature
|
||||
* =========== ========================= ============= ====================
|
||||
* lockli.c pthread_mutexattr_settype <pthread.h> _XOPEN_SOURCE >= 500
|
||||
* prmci3li.c REG_EAX etc. <ucontext.h> _GNU_SOURCE
|
||||
* prmci6li.c REG_RAX etc. <ucontext.h> _GNU_SOURCE
|
||||
* prmcix.h stack_t, siginfo_t <signal.h> _XOPEN_SOURCE
|

* pthrdext.c sigaction etc. <signal.h> _XOPEN_SOURCE
|
||||
* vmix.c MAP_ANON <sys/mman.h> _GNU_SOURCE
|
||||
*
|
||||
* Unfortunately it's not possible to localize these feature
|
||||
* specifications around the individual headers: all headers share a
|
||||
* common set of features (via <feature.h>) and so all sources in the
|
||||
* same compilation unit must turn on the same set of features.
