-Building wxGTK on Cygwin               {#gtk_cygwin}
---------------------------
-
-The normal build instructions should work fine on Cygwin. The one difference
-with Cygwin is that when using the "--enable-shared" configure option (which
-is the default) the API is exported explicitly using `__declspec(dllexport)`
-rather than all global symbols being available.
-
-This shouldn't make a difference using the library and should be a little
-more efficient. However if an export attribute has been missed somewhere you
-will see linking errors. If this happens then you can work around the
-problem by setting `LDFLAGS=-Wl,--export-all-symbols`. Please also let us know
-about it on the wx-dev mailing list.
