I'm on Mageia Linux Cauldron x86-64 on an Intel Core i3 machine. Here are some
offending invocations of gcc:
* /usr/bin/gcc -std=gnu99 -Wall -Wextra -O2 -fno-strict-aliasing -fwrapv -o
154.exe euler-154.c
* /usr/bin/gcc -std=gnu99 -Wall -Wextra -O2 -g -o 154.exe euler-154.c
* /usr/bin/gcc -std=gnu99 -O3 -Wall -fwhole-program -flto -fvisibility=hidden
-fomit-frame-pointer -o 154.exe euler-154.c
I'm not getting any errors or warnings.
