Have you checked in src/auto/config.log why AvailabilityMacros.h is not
found?
You did do "make reconfigure" or "make distclean"?
AvailabilityMacros.h is found, and HAVE_AVAILABILITY_MACROS_H should be
set. It just isn't when I get to line 807 in os_unix.c. This looks like
a typo somewhere, but autoconf is not my forte.
In config.log:
206 configure:4266: checking AvailabilityMacros.h usability
207 configure:4266: gcc -c -g -O2 -I/sw/include conftest.c >&5
208 configure:4266: $? = 0
209 configure:4266: result: yes
210 configure:4266: checking AvailabilityMacros.h presence
211 configure:4266: gcc -E -I/sw/include conftest.c
212 configure:4266: $? = 0
213 configure:4266: result: yes
214 configure:4266: checking for AvailabilityMacros.h
215 configure:4266: result: yes
And every build is a clean build, so I shouldn't have to make
reconfigure.
