GCC error when installing ncurses on OS X 10.8

I'm trying to install ncurses 5.9 on OS X 10.8 with GCC 4.9 installed. No errors or warnings show up when I run ./configure in the ncurses directory, but when I run make, I get gcc: error: unrecognized command line option ‘-no-cpp-precomp’. Upon googling the issue (and trying it out), I found that --no-cpp-precomp (with two dashes, i.e in long flag form) is a valid command.

I'm not sure what was prompting GCC to run the invalid command – whether it was make, or if it was a command specified in ncurses itself.

Is there any way to fix this? If so, how?

EDIT: I tried changing the reference in the ./configure file from -no-cpp-precomp to --no-cpp-precomp manually, using a text editor, and was met with this, despite GCC seemingly accepting the --no-cpp-precomp option. After that, I tried running autoreconf, and got this:

configure:6558: error: possibly undefined macro: AC_DIVERT_HELP
      If this token and others are legitimate, please use m4_pattern_allow.
      See the Autoconf documentation.
autoreconf: /opt/local/bin/autoconf failed with exit status: 1

After running it with the m4_pattern_allow option:

autoreconf: 'configure.ac' or 'configure.in' is required

After running ./configure && make anyway:

cd man && make DESTDIR="" all
sh ./MKterminfo.sh ./terminfo.head ./../include/Caps ./terminfo.tail >terminfo.5
cd include && make DESTDIR="" all
cat curses.head >curses.h
AWK=gawk sh ./MKkey_defs.sh ./Caps >>curses.h
sh -c 'if test "chtype" = "cchar_t" ; then cat ./curses.wide >>curses.h ; fi'
cat ./curses.tail >>curses.h
gawk -f MKterm.h.awk ./Caps > term.h
sh ./edit_cfg.sh ../include/ncurses_cfg.h term.h

I realize this is very old now, but since I'm running into the same issue (need to build on Mac Yosemite 10.10 with GCC 4.9), maybe it'll help someone else too. It looks like the configure script is detecting that it's a Mac and assuming clang is used, even though the 'gcc' from the PATH is GNU. Seems they fixed the detection logic in newer versions. I've found the same issue in Boost 1.37 and it was fixed (somewhere before) Boost 1.55.

It looks like this has been fixed in the latest patches to ncurses 5.9

The 5.9 source can be found here: ftp://invisible-island.net/ncurses/ncurses-5.9.tar.gz

The latest patches are here: ftp://invisible-island.net/ncurses/5.9/ but the latest rollup patch appears to have the fix: ftp://invisible-island.net/ncurses/5.9/patch-5.9-20130504.sh.gz

To apply the patch, get the 2 files above then:

$ tar xvf ncurses-5.9.tar.gz
$ cd ncurses-5.9
$ gzip -dc ../patch-5.9-20130504.sh.gz | sh

--no-cpp-precomp is an obsolete Apple GCC option it should generate a warnning not an error but if -Werror flag is passed to the compiler it will fail on warnings, either way, you will have to remove it manually from the build scripts and then run autoreconf or you could just remove it from the configure script directly.
