Well, I'm not sure what is up with the const thing since thats bog
standard C89 even, but the structure initializers and the Intel
compiler are a matter of using the GCC extension vs C99:

-     [SMINFO_MASTER] "SMINFO_MASTER",
+     [SMINFO_MASTER] = "SMINFO_MASTER",

And similarly anything using the 'field: value' should be '.field =
value' for C99. (make sure C99 support is turned on too!)

Compiling with -std=c99 on Linux will catch several of these issues,
and purging them agressively is generally a good idea.

Actually -std=c99 -D_XOPEN_SOURCE=600 is good option set for portable
code written to modern standards (ie SUSv3 and C99) as it purges some
of the uncommon and BSD calls from the library headers and tends to
keep things cleaner. (Though sometimes you need to use _GNU_SOURCE on
some files to access some special functions :()

But it is all kind of moot if you are attempting to compile without
some POSIX API emulation layer for Windows (SFU, cygwin, etc).
That makes things extra hard, and I'm not sure it is worthwhile for
this particular application. :)

Ie if you are willing to use MS's SFU you get gcc and a POSIX
compatibility library as part of the SDK install and alot of
problems go away.
