[PATCH 3/4] DJGPP fix: remove both conftest and conftest.exe.

[Ralf Wildenhues]

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.

This patch is obvious (the semantics are even documented in the comments
of the macro).  I will commit it soon.
