Changes to build bash-1.12 under SCO Unix 3.2v4.0:

In the M_UNIX section of machines.h:

#    if !defined (HAVE_GCC)
#      define REQUIRED_LIBRARIES -lPW -lmalloc -lc_s
#    endif /* !HAVE_GCC */

SCO Unix has alloca() in -lPW.
malloc pulls in a faster malloc than the one in -lc
-lc_s uses a shared library version of the c runtimes

jobs.c:

The ' #if defined (SCO) ' sections make bash hang on the call to waitpid.
I removed the SCO conditional code, and bash no longer hangs.
Apparently, SCO fixed the sigsuspend() call in 3.2v4.0, and somehow broke
something that the workaround uses.

lib/readline/readline.c:

In rl_search_history,
  /* Initialize search parameters. */
#if 1
  strncpy(search_string, the_line, 127);
  search_string[127] = '\0';
  search_string_index = strlen(search_string);
#else
  *search_string = '\0';
  search_string_index = 0;
#endif

So history searches start with the text already on the line as the pattern.
