#2318 strdup not declared in c99

[Maarten Brock]

Since the sdld linker is built with --std=c99 gcc no longer knows about strdup() and generates lots of warnings.

I suggest everyone to build sdcc with make > /dev/null so you actually get to see all warnings and fix them before doing a commit.

On derna, the --std=c99 option seems to cause the mingw32 build to completely fail because _MAX_FNAME and _splitpath() become missing and they are needed in sdld.c

Is the only reason for --std=c99 to fix the problem with a duplicate definition of strndup()? If so, we could update configure.in to check for an existing system definition and bracket the local definition with #ifndef HAVE_STRNDUP rather than change the dialect.

Fixed in SDCC 3.4.1 #9119.

Oops, I think I closed this too early. The latest solution breaks the MSVC build because it has no sdccconf.h.

Fixed in #9153.
