Solaris compilation Failure: fatal error: sys/mcontext.h: No such file or directory

[Shawn Ellis]

The compilation fails when building sbcl-2.0.4 on Solaris because mcontext.h doesn't exist. I'm able to reproduce this problem on Solaris 10 and 11. I've attached a patch that removes mcontext.h and everything builds cleanly.
gcc -m64 -g -O2 -Wall -D__EXTENSIONS__ -D_POSIX_C_SOURCE=199506L -DSVR4 -D_REENTRANT -fno-omit-frame-pointer -I. -c -o x86-64-sunos-os.o x86-64-sunos-os.c
x86-64-sunos-os.c:15:10: fatal error: sys/mcontext.h: No such file or directory
 #include <sys/mcontext.h>
          ^~~~~~~~~~~~~~~~
compilation terminated.
gmake: *** [<builtin>: x86-64-sunos-os.o] Error 1

How to Reproduce:

1. sh ./make.sh on Solaris

SunOS epinard 5.11 11.4.0.15.0 i86pc i386 i86pc

That include is there for a reason, simply removing it might break other OS configurations.

Ok, I had thought that the file was Solaris specific and wouldn't be used with other operating systems.

[Stas Boukarev (stassats)]

I mean different Solaris configurations. But I just tested it on OpenIndiana, and it seems to not need these includes.

Thanks! SBCL builds cleanly on Solaris 11 now.
