[Ecls-list] cygwin

[I removed fricas-devel from the CC, because I am not subscribed]

Hi Martin,

I have fixed a couple of problems with the cygwin port. The log is
below, but everything is related to yet another dlopen() problem:
namely, it does not like filenames without file extensions. This
prevented ECL from making a copy of every fasl it loads, so that when
a file is recompiled it cannot be reloaded. I think this might explain
some of your problems when building fricas with ECL: I presume fricas
compiles and recompiles itself several times.

    src/c/load.d:
    * In cygwin, FASL files can not lack a file extension, because dlopen()
      then looks for a file ending in .dll and fails.
    * In cygwin, files that are dlopen'ed must have executable permissions.
