While building the 8.0 releases on FreeBSD, I encountered the following
error in the regression tests, where ompt/misc/interoperability.cpp
failed to compile, with:
projects/openmp/runtime/test/ompt/misc/interoperability.cpp:7:10: fatal error: 'alloca.h' file not found #include <alloca.h> ^~~~~~~~~~
Like on NetBSD, alloca(3) is defined in <stdlib.h> instead.
