Can you send the config.log for this one?

I do not remember to need such many flags for compling Ipopt on an Intel 
Mac. The -no-cpp-precomp looks suspicious to me. Also it should be 
CXX=g++, not gcc.

 From the config.log you send, the problem seem to be:
/usr/include/mach/i386/_structs.h:91: error: type of bit-field 
'__invalid' is a GCC extension

What is the failure?

Yes. After make install you get several header files in the include/coin 
subdirectory of your installation. When you use the Ipopt library, best 
is to use also the header files from there. The config_ipopt.h is system 
specific and contains the specifica of your build platform.

Best,
