Perhaps this is due to a bug in the HP-UX C compiler?
What does it do with the following text?

#ifdef __STDC__
/\
* A comment with backslash-newlines in it. %{ %} *\
\
/
char str[] = "\\
" A string with backslash-newlines in it %{ %} \\
"";
char apostrophe = '\\
\
'\
';
#endif

Assuming the HP-UX compiler mishandles the above example, is there a
simple way to avoid the compiler bug?  For example, perhaps we could
remove the lines that contain solitary backslashes?
