I simplistically searched for the string "long" & it was not found in the config.log. As a guess, I'd say the failure to compute the size of the long long was a collateral damage effect from some other failure, such as the one I sent Ian: " configure:5545: gcc -o conftest -g -O2 conftest.c -L/usr/local/lib/ -L/usr/local/lib/ -L/usr/local/lib/ -lmpc -lmpfr -lgmp >&5 configure:5545: $? = 0 configure:5546: result: yes configure:5730: checking for PWL_handle_timeout in -lpwl configure:5755: gcc -o conftest -g -O2 conftest.c -lpwl >&5 ld: library not found for -lpwl collect2: ld returned 1 exit status configure:5755: $? = 1 configure: failed program was: | /* confdefs.h */ | #define PACKAGE_NAME "" | #define PACKAGE_TARNAME "" | #define PACKAGE_VERSION "" | #define PACKAGE_STRING "" | #define PACKAGE_BUGREPORT "" | #define PACKAGE_URL "" | #define LT_OBJDIR ".libs/" | /* end confdefs.h. */ | | /* Override any GCC internal prototype to avoid an error. | Use char because int might match the return type of a GCC | builtin and then its argument prototype would still apply. */ | #ifdef __cplusplus | extern "C" | #endif | char PWL_handle_timeout (); | int | main () | { | return PWL_handle_timeout (); | ; | return 0; | } configure:5764: result: no configure:5778: checking for version 0.11 (revision 0 or later) of PPL configure:5795: gcc -c -g -O2 conftest.c >&5 conftest.c:10:19: fatal error: ppl_c.h: No such file or directory compilation terminated. configure:5795: $? = 1 configure: failed program was: | /* confdefs.h */ | #define PACKAGE_NAME "" | #define PACKAGE_TARNAME "" | #define PACKAGE_VERSION "" | #define PACKAGE_STRING "" | #define PACKAGE_BUGREPORT "" | #define PACKAGE_URL "" | #define LT_OBJDIR ".libs/" | /* end confdefs.h. */ | #include "ppl_c.h" | int | main () | { | | #if PPL_VERSION_MAJOR != 0 || PPL_VERSION_MINOR < 11 | choke me | #endif | | ; | return 0; | } configure:5799: result: no "
