PR 17185
PR 17185 describes a problem with using gdb+guile with libgc 7.4.0.
The symptom is a hang in sigsuspend.
[The thread referenced in the PR has the details.]
It's not clear what the right fix is, or even where the bug is yet.
This patch applies the same workaround Guile has applied.
There is no functionality or real performance loss with this,
and Guile has been using it for awhile.
* configure.ac: Add check for header gc/gc.h.
Add check for function setenv.
* configure: Regenerate.
* config.in: Regenerate.
* guile/guile.c (_initialize_guile): Add workaround for libgc 7.4.0.
