Mattias, It looks like the development branch of GCC 4.5 has swithce a CPP processor include file missing from just a wraning to an error.
The configure in HylaFAX is looking for the include files for the fchmod
declaration:
$CXX -E t.c++ \
| sed -e '/\/\*/,/\*\//d' -e 's;//.*$;;'
| awk '{while($0~/[,(][ \t]*$/){printf"%s",$0;getline}print}' \
| grep "fchmod[ ]*(.*)"
where t.c++ is (in this case):
#include "unistd.h"
#include "libc.h"
#include "sys/stat.h"
Every other complier we've come across (GCC releases, Sun CC, Sco CC,
AIX CC, HUPX CC) issue pre-processor warnings on files not found (most
don't find "libc.h"), but none of them issue a fatal error that the GCC
HEAD branch is:
t.c++:2:18: fatal error: libc.h: No such file or directory
For instance, any released GCC (4.4 and earlier) does:
t.c++:2:18: error: libc.h: No such file or directory
But none of their pre-processors *stop* there, they finish including
sys/stat.h, which allows configure to see the fchmod declaration. They
all exit with a non-zero exit, but all preprocess the rest of the input.
I'ld say this is a bug with GCC HEAD's pre-processor.
