+
+mingw-cross-env specific workaround for OSX Lion's new ASLR
+causing problems with pre-compiled headers.
+
+1. more recent native compilers don't solve the problem
+2. there isn't an equivalent sysctl for "kernel.randomize_va_space"
+3. there isn't an equivalent command for "setarch -R"
+4. Apple's version of gcc (based on 4.2) uses custom Makefiles that set "-fno-pic"
+
+Patch below achieves a similar result to 4, without drifting
+too far from standard gcc.
