DJGPP bash 2.04 has a bug in that `return $ac_retval' done in a
shell function which also contains a command substitution causes
the shell to barf. For more details and a fix see:
<http://www.delorie.com/djgpp/mail-archives/browse.cgi?p=djgpp-workers/2009/09/09/03:35:08>
Possible workaround include putting the `return' in a subshell
or calling another function to set the status.
* lib/autoconf/general.m4 (_AC_PREPROC_IFELSE_BODY)
(_AC_COMPILE_IFELSE_BODY, _AC_LINK_IFELSE_BODY)
(_AC_RUN_IFELSE_BODY, _AC_COMPUTE_INT_BODY): Use AS_SET_STATUS
instead of `return'.
* doc/autoconf.texi (Common Shell Constructs, Shell Functions):
Document the issue.
* THANKS: Update.

The DJGPP compiler may create both `a.out' and `a.exe' without -o,
and both `conftest' and `conftest.exe' with `-o conftest', but not
with `-o conftest.exe'.
* lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Also remove
`conftest' without $ac_exeext suffix.

* lib/autoconf/general.m4 (AC_SITE_LOAD, AC_CACHE_LOAD): Do not
load the cache or site file if it is `/dev/null', as DJGPP treats
it as a regular file, but the shell then warns about it later.
Fixes several test suite failures on DJGPP.
