building gcc with gcc (targeting OS X on linux) causes the following errors:
error 1:
g++ -g -O2 -DIN_GCC -DCROSS_DIRECTORY_STRUCTURE -fno-exceptions -fno-rtti -fasynchronous-unwind-tables -W -Wall -Wno-narrowing -Wwrite-strings -Wcast-qual -Wmissing-format-attribute -pedantic -Wno-long-long -Wno-variadic-macros -Wno-overlength-strings -DHAVE_CONFIG_H -static-libstdc++ -static-libgcc -o xg++ \

error 2:

cc1plus: error: unrecognized command line option '-mmacosx-version-min=10.4'
after fixing the -mmacosx-version-min issue in the gcc/specs file, I get the following weird error (gmp is indeed installed):
g++ -c -DIN_GCC_FRONTEND -g -DIN_GCC -DCROSS_DIRECTORY_STRUCTURE -fno-exceptions -fno-rtti -fasynchronous-unwind-tables -W -Wall -Wno-narrowing -Wwrite-strings -Wcast-qual -Wmissing-format-attribute -pedantic -Wno-long-long -Wno-variadic-macros -Wno-overlength-strings -DHAVE_CONFIG_H -I. -I. -I../../gcc -I../../gcc/. -I../../gcc/../include -I../../gcc/../libcpp/include -I../../gcc/../libdecnumber -I../../gcc/../libdecnumber/dpd -I../libdecnumber -I../../gcc/../libbacktrace cc1-checksum.c -o cc1-checksum.o
In file included from cc1-checksum.c:2:0:
../../gcc/system.h:641:17: fatal error: gmp.h: No such file or directory
#include <gmp.h>
all these errors do not appear when clang is used for building gcc.
