When gcc goes to build libjava, the configure script has a bug in it. This snippet causes the bug: /* Override any gcc2 internal prototype to avoid an error. */ #ifdef __cplusplus extern "C" #endif /* We use char because int might match the return type of a gcc2 builtin and then its argument prototype would still apply. */ char XTestQueryExtension (); int main () { XTestQueryExtension (); ; return 0; } Now, when I manually compile this code block (linking with Xtst), the result is a segfault. Because this does not return 0 by definition in either compile or run, the code proceeds to the following block: { { echo "$as_me:$LINENO: error: libXtst not found, required by java.awt.Robot" >&5 echo "$as_me: error: libXtst not found, required by java.awt.Robot" >&2;} { (exit 1); exit 1; }; }

same error here with sys-devel/gcc-4.3.2 on amd64
