Sun Studio 12 support DOS text (e.g. CR\LF) for line continuation ?

Question

I moved up to Sun Studio 12 hoping that I could solve a age old problem that allows me to share my code via NFS across multiple systems. AIX and GCC Linux precompilers and compilers have not problem with a code like this:
#ifndef FSIBITON^M
#define FSIBITON(x) \^M
(long)( \^M
( ~(unsigned long)0 >> x ) & \^M
( ~(unsigned long)0 << ((sizeof(long)*8) - (x+1)) ) \^M
)^M
#endif^M
(where ^M is the CR character)
but for Solaris with the Sun Solaris compilers I have always had to copy the tree and convert to UNIX text.
The line continuations are there for z/OS MVS record length limits to avoid having to modify default systems to build on that platform.
Error:
"/release/rel122/rps100/fsilib/unix/../h/fsi.h", line 118: token not allowed in directive: \
Is there some undocumented flag/option I can use to get past this error? I hope so. Otherwise have to go back to coping lots and lots of code around, converting to Unix text as I do it, preserve the date based on the original file and then copy the binaries back to staging afterwards. On AIX and Linux and Windows they can all build in parallel from the SCM export.

Sorry, I don't know of a way around this exact issue.
Studio compilers will ignore the CR in a CR/LF sequence, but the C compiler does not accept what looks like an escaped CR. (The C++ compiler does accept what was intended as an escaped newline sequence.)
Is the CR actually necessary? I thought that on systems using CR/LF as the default newline would accept LF as a newline as well in source code.
If you have a Studio support contract with Oracle, you can file a request for enhancement (RFE) on the C compiler via your support channel to address your problem.
