It breaks bootstrap with non GNU compilers, at least with Sun CC. You can
reproduce the failure by bootstrapping with 'gcc -fkeep-inline-functions':
gcc -m64 -fkeep-inline-functions -g -DENABLE_CHECKING
-DENABLE_ASSERT_CHECKING -DIN_GCC -W -Wall -Wwrite-strings
-Wstrict-prototypes -Wmissing-prototypes -fno-common -DHAVE_CONFIG_H
