A unified solution is certainly desirable. But perhaps we should find out how 
urgent a solution to this problem is before you decide to take on this 
problem for the next release. DJGPP's Bash has a solution (TEST_FINDS_EXE as 
mentioned), Cygwin (I've been told) has a similiar solution, and I don't know 
about EMX.

I'm convinced there is a good way to do this without resorting to uname, yet 
nobody has yet to find one.

I ran autoheader with '-d' to preserve traces.sh.

traces.sh:
m4trace:c:/djgpp/tmp/ac7778/stdin:2: -1- AC_CONFIG_HEADERS(config.h)
m4trace:c:/djgpp/tmp/ac7778/stdin:3: -1- AC_DEFINE(this, "whatever you 
want.")
