# Target operating system. Valid values are:
# LINUX FREEBSD OPENBSD NETBSD SOLARIS UNIXWARE BEOS ATHEOS

OS = LINUX

# Optimization method (SIZE/SPEED)

# Target executable format (ELF/AOUT)

EXECUTABLE = ELF

# Use hacked ELF for smaller binaries (when possible)
# Disable if you have trouble running resulting executables.

# Write version stamp into executables

#STAMP = y

# Use custom startup code
# Enable along with SYSCALL=LIBC if gcc fails with -nostartfiles
# (when linker can't find some external symbols required by libc);
# you may also need this with OS=BEOS.
