The configure script searches the command path first for executables named "latex", then for executables named "latex2e", and if it finds one tests it by running it against a temporary file it creates (chklatex.ltx). The problem is that (a) Cygwin apparently puts /usr/bin ahead of anything on the Windows PATH when constructing the PATH environment variable used by its shells, (b) Cygwin's /bin directory (to which /usr/bin apparently maps) contains a version of latex that apparently fails the usability test and (c) the script stops looking for executables named "latex" the first time it finds one (even if that one is unusable). The solution was to get rid of the latex.exe file in /usr/bin. IIRC, one can opt not to install Cygwin's LaTeX module, which clearly I should have done. -- Paul
