Mono compile on Solaris

Question

I am trying to compile mono on Solaris 10. I have tried a lot of version from 2.11.4 to the todays latest 5.xx versions. But I have the failure all the time.

I am using Sun-Fire-v240 hardware which has SPARC processor. Also, OS version is Oracle Solaris 10 1/13 s10s_u11wos_24a SPARC

The problem that i am getting is this:

checking for PTHREAD_MUTEX_RECURSIVE... no
configure: error: Posix system lacks support for recursive mutexes

is there a way to compile mono for Solaris, I have been searching this problem for a while, but I had no working result for my case. I am not that good over UNIX systems, so I guess i am missing something...

Thank you. Best Regards, Orhan.

This appears to be a two-year-old Mono bug, Bug 31999 - C99 and XPG5 don't match on Solaris 10+:

checking for PTHREAD_MUTEX_RECURSIVE... no configure: error: Posix
system lacks support for recursive mutexes

which is incorrect. In config.log I find

configure:22190: checking for PTHREAD_MUTEX_RECURSIVE

This error is an artefact of the fact that configure.ac has

  CPPFLAGS="$CPPFLAGS -D_XOPEN_SOURCE=500"

while on Solaris 10 and up C99 can only be used with XPG6/_XOPEN_SOURCE=600. Completely omitting the _XOPEN_SOURCE definition isn't an option since without it, <sys/socket.h> struct msghdr lacks the msg_flags member.
