[flext] flext newbie has build problems on osx

[Hannes Breitschädel]

Compiling now worked, there is still a linker issue. 

I learned the following things I am glad to share with the flext community.

Tips on builing flext on OSX for newbies:
1) it is possible to drag and drop folders from finder into the terminal window. I it is also possible to drag them into a text file. Safes a lot of time entering long paths!!
2) command + T clears terminal output window.
3) I had to define some paths for the compiler:
	UFLAGS += -I/usr/include/c++/4.2.1
	UFLAGS += -I/usr/llvm-gcc-4.2/lib/gcc/i686-apple-darwin10/4.2.1/include
	UFLAGS += -I/usr/include/c++/4.2.1/i686-apple-darwin10
	UFLAGS += -I/usr/include

4) I changed the flext source file "flutil.cpp" completely: 
	removed:	#include <Carbon/Carbon.h> 

 and reduced the following two functions to		
	void flext::CopyMem(void *dst,const void *src,int bytes) 
	{
	    memmove(dst,src,bytes);
	}

	void flext::ZeroMem(void *dst,int bytes) 
	{
	    memset(dst,0,bytes);
	}

5) /usr on osx is hidden and spotlight does not search there.

	to display hidden files in finder type:
	defaults write com.apple.finder AppleShowAllFiles TRUE
	killall Finder

	to do the reverse:
	defaults write com.apple.finder AppleShowAllFiles FALSE
	killall Finder

6) to search within hidden paths:
	select the hidden folder in finder,
	type command + F
	enter search name
	AND select the hidden folder (usually to the right of "This Mac")


now compilation works. The linker throws this error:
	ld: library not found for -ldylib1.o
