 *
 *  There *used* to be a number of similar problems in various OSes:

 *  Turning // comments into normal comments trashes this IRIX 4.0.1
 *  header file, which embeds // comments inside multi-line

 *  just throwing away the // comments.

 *  Same problem with a file from SunOS 4.1.3 : a header file containing

 *  There is a similar problem with the VxWorks drv/netif/if_med.h file.

 *  And also with the HP-UX 10 and HP-UX 11 sys/pci.h file

 *  Now that we delete the // comments instead of converting them to / * * /,
 *  traditional hacks like irix_bogus_cxx_cmnt, no longer work (which
 *  strangely enough was also used on alpha-dec-osf4.0d).  If we skip the
 *  hack whenever we see ``"//"' ', then the need for the secondary hack
 *  disappears.  Note: it is painful to ensure that the first quote
 *  exists, so we just check for the trailing quote directly abutting
 *  the //.  Note: We should never touch a line that has // completely
 *  within quotes but this is somewhat hard to check for.

I think this patch needs some more thinking.
This is from SVR4.2 (With '#' replaced with '@').
Perhaps we could do without the "/matherr/a" entries?
Can we bypass the entire fix if someone was astute
enough to have '#ifdef __cplusplus' anywhere in the file?
