[Cscope-devel] Mods for osr5 and uw7 builds

[Mike Hopkirk(hops) <ho...@sc...>]

I added Makefiles for building on osr5 and uw7 (svr5)
 and corresponding changes to 2 source files.
Added a contrib dir, README for its contents and a wrapper script (ocs) from
osd eng that supports cscope databases for a recursive directory set
(and control over where database go ...)

THe osr5 (and uw7) builds use flex. It will build and run with the
native lex but it seems to be failing to strip out comment lines for 
the created database.

Petr it may be workwhile to supply the original (non flexed) scanner.l file
(in all its twisted glory) for those that want to use the AT&T lex to 
build this ....


build/Makefile.osr5
        Change macro for LIBS (curses and libl)
        Change macros for DEFLIST (define osr5 )
        Add macros for lexer binary and lex flags 
        allow possibility of both lex and flex use, default to flex
        parameterise flag for static build
        add CC description that includes -belf and allow possibility of gcc.

build/Makefile.svr5
        define STRERROR so uses strerror fn rather than str_errlist
        ditto lex/flex above

common/display.c
        remove errno sys_errlist extern, include errno.h instead
        myperror() ifdef on STRERROR use of strerror instead of sys_errlist 

common/exec.c
        remove dfn pid_t - include sys/types.h

new :
    contrib
    contrib/README
    contrib/ocs - shell wrapper for cscope hadling dir recursion etc
