Hi Gaius,

Unfortunately, these changes break the build on Mac OS X (at least 10.5/Intel):

gcc -g -DIN_GCC -W -Wall -Wwrite-strings -Wstrict-prototypes - Wmissing-prototypes -DHAVE_CONFIG_H -o stage1/gm2/cc1gm2 gm2/ gccgm2.o gm2/gm2builtins.o gm2/gm2-lang.o gm2/gm2except.o gm2/stor- layout.o gm2/m2pp.o gm2/gm2-compiler-boot/gm2.a gm2/gm2-libs-boot/ libgm2.a gm2/p2c/p2c-src/src/libp2c.a \ gm2/gm2-compiler-boot/m2flex.o main.o libbackend.a ../libcpp/libcpp.a ../libcpp/libcpp.a -lintl -liconv ../ libiberty/libiberty.a -lm

I couldn't find any reference to any flavor of exp10() in the 7 September 2007 draft of C99 and I don't recall seeing it in earlier C standards. Perhaps pow() is needed instead.
