Hi Jim and all,
On a CentOS 5.4 system, compiling with gcc 4.4.2, configure goes into an
infinite loop here:
checking whether btowc(EOF) is correct...
Running gdb on conftest gets a backtrace like this:
#0 0x080491d1 in btowc (__c=-1) at /usr/include/wchar.h:331
#1 0x08049431 in btowc () at /usr/include/wchar.h:332
#2 main () at conftest.c:276
Where that line 331 is:
331 { return (__builtin_constant_p (__c) && __c >= '\0' && __c <= '\x7f'
This does not happen with other versions of gcc. I can't tell if it's a
gcc bug or a system include file bug or something actually in coreutils,
but here's the report anyway. It was pretty unsettling to have
configure hang.
