Splendid!

I've attached a patch to RT #49433, which should fix that build issue when it's applied. At least, that patch works for me on Windows 10 with a sh.exe in a directory listed in $ENV{PATH}. Where, by "works" I mean that the Build.PL bails out with an error message instructing me to edit $ENV{PATH}.

Subject: [PATCH] Bail out of building if sh.exe or cc1.exe are found o
+n the
 path

This addresses # RT #49433 , RT #62451

The workaround is to adjust $PATH / $ENV{PATH} to exclude directories
in which sh.exe or cc1.exe is found. Another workaround is to set
$ENV{WX_IGNOREPATH} to a true value to disable this check.
