[Daniel Herring]

Hi Faré,

Does the attached patch improve things on your system?

To apply the patch, run

$ git am 0001-fixes-for-the-detection-of-GC_start_call_back.patch

Then re-run configure and build.

Later,
Daniel

Subject: [PATCH] fixes for the detection of GC_start_call_back

- HAVE_GC_SET_START_CALLBACK was defined unconditionally
- there was no AC_DEFINE if system_boehm was false
- there was a typo in one usage site of this macro

see 6b754564f1d1a2d320b1fd46f0c0da2e623862c1
