From 43a91548b31101b95bc2b2e29ada872bb3d9590e Mon Sep 17 00:00:00 2001 From: "jan.nijtmans" Date: Thu, 10 Oct 2013 14:13:51 +0000 Subject: Fix for bug [f51efe99a7]: MinGW build fails on current checkin. And a new test-case which makes the problem visible on UNIX as well. --- generic/tclOO.h | 5 +- generic/tclOODecls.h | 2 + generic/tclOOStubLib.c | 2 + tests/load.test | 6 +++ unix/dltest/Makefile.in | 13 ++++- unix/dltest/pkgooa.c | 138 ++++++++++++++++++++++++++++++++++++++++++++++++ 6 files changed, 161 insertions(+), 5 deletions(-) create mode 100644 unix/dltest/pkgooa.c diff --git a/generic/tclOO.h b/generic/tclOO.h index 41be168..a6e8a22 100644 --- a/generic/tclOO.h +++ b/generic/tclOO.h @@ -37,13 +37,12 @@ extern "C" { #endif -#if (defined(USE_TCLOO_STUBS) || defined(USE_TCL_STUBS)) extern const char *TclOOInitializeStubs( Tcl_Interp *, const char *version);
