| Description: |
With a few changes, tcl.m4 can cover the scenario of using a native minGW compiler from a cygwin shell/utilities environment. Since Cygwin is a target platform in its own right, this is a form of cross-compilation. The included patch seems to be sufficient to enable this mode of building Tcl. See Tcl issue d995ca52091dd8db7db415e4256e903093ee043a for a companion patch. | |||

Applied (with some tweaking) to core-8-5-branch and trunk. jan.nijtmans added on 2015-10-05 07:38:14: Thanks! Actually, I have the building environment working to cross-compile with mingw under cygwin, but I tweaked the environment a little bit to accomplish this. Your patch looks like a better solution. pooryorick added on 2015-10-05 05:44:14:
