[mapserver-users] compiling error core.c in mapcache with cygwin

[Gery .]

Hello,

When installing mapcache in cygwin, `make` produced:

    /opt/mapcache/mapcache-rel-1-2-1/lib/core.c: In function ‘mapcache_prefetch_tiles’:
    /opt/mapcache/mapcache-rel-1-2-1/lib/core.c:81:3: error: unknown type name ‘apr_thread_t’
       apr_thread_t **threads;
       ^
    /opt/mapcache/mapcache-rel-1-2-1/lib/core.c:82:3: error: unknown type name ‘apr_threadattr_t’
       apr_threadattr_t *thread_attrs;
       ^
    /opt/mapcache/mapcache-rel-1-2-1/lib/core.c:83:7: warning: unused variable ‘nthreads’ [-Wunused-variable]
       int nthreads;
           ^
    /opt/mapcache/mapcache-rel-1-2-1/lib/core.c:82:21: warning: unused variable ‘thread_attrs’ [-Wunused-variable]
       apr_threadattr_t *thread_attrs;
                         ^
    /opt/mapcache/mapcache-rel-1-2-1/lib/core.c:81:18: warning: unused variable ‘threads’ [-Wunused-variable]
       apr_thread_t **threads;
                      ^

I searched for some hints about this error but didn't find anything. Looking for `apr_thread_t` and cygwin, I found some pages pointing to an error with apache, but not really sure if apache has something to do here.

thanks for any hints on this,

Gery
