upgrade of doxygen-1.5.7 error

[Jonathan Stickel]

I get this error when upgrading doxygen to 1.5.7:

c++ -c -pipe -D__FreeBSD__=6 -Wall -W -O2 -I../qtools -o 
../objects/portable.o portable.cpp
portable.cpp: In function 'size_t portable_iconv(void*, const char**, 
size_t*, char**, size_t*)':
portable.cpp:392: error: invalid conversion from 'char**' to 'const char**'
portable.cpp:392: error:   initializing argument 2 of 'size_t 
libiconv(void*, const char**, size_t*, char**, size_t*)'
gmake[2]: *** [../objects/portable.o] Error 1

I have Mac OS 10.4.11.  Any suggestions?

Thanks,
Jonathan
