# Problems in early version of the assembler have been fixed (-DNO_BUGS).
# There are peculiar problems with the include files that require __STDC__
# to be defined as 0.  This results in sigset_t being defined which otherwise
# results in a problem when <wait.h> includes <siginfo.h>.

# The CI5 compiler does not provide alloca.
