All I would be doing is killing trailing spaces, and turning space-tab
into tab-space (inside sed regexes) or plain tab (if leading indentation),
which should not affect GNU Coding Standard compliance.  But yes, I'll be
careful, and post what I do.

'make check' in m4 CVS head has worked under cygwin for some time now.
However, installing with shared libraries preloaded doesn't quite work,
because libtool still installs the module .dlls under libexec, which is
not on PATH, while giving the m4 binary has a hardcoded dependency on
those .dlls.  By Windows rules, a preloaded .dll must be on the PATH (I
can get through the testsuite by adding libexec to my path, or by copying
the built .dll librares into bin alongside m4.exe).  Installing a
static-only build works, as does installing with nothing preloaded.
