?S: This variable conditionally defines the CSH symbol, which
?S: indicates to the C program that the C-shell exists.
?S:.
?S:full_csh:
?S: This variable contains the full pathname to 'csh', whether or
?S: not the user has specified 'portability'. This is only used
?S: in the compiled C program, and we assume that all systems whic
?S: can share this executable will have the same full pathname to
?S: 'csh.'

?X: Yes, I know about the C symbol PORTABLE, but I think csh
?X: is unlikely to move, and I'm too lazy to add all the
?X: #ifdef PORTABLE sections to the perl source.
