The reason is that the configure script detected gcc before the compiler from __GMP_CC was chosen and did some settings related to gcc (due to some autoconf macro), such as selecting gcc-specific options. Main change from the RC2 to the RC3: - Fixed the way $CC / $CFLAGS are got from gmp.h (__GMP_CC / __GMP_CFLAGS). Changes from version 2.4.1 to version 2.4.2: - Security fix in formatted output functions (buffer overflow). - Formatted output functions: 6 is now the default value for empty precision field with %Rf. - Better portability of configure script. - Detection of intmax_t and uintmax_t types. - Improved documentation: mpfr_get_z_exp, mpfr_strtofr, mpfr_get_str and formatted output functions. - Improved message in case of assertion failure. - Test coverage: 97.0% lines of code. - Updated tcmp_ld test to really test the long double. - Some documentation files are installed in $docdir. - Removed mpfr_init_cache (unused and undocumented function). - Fixed the way $CC / $CFLAGS are got from gmp.h (__GMP_CC / __GMP_CFLAGS). - Bug fixes. - Also note that GCC 4.4.0 (only this obsolete version) does not build MPFR 2.4.2 correctly; this is detected by "make check" (failures in tget_z and tpow_all). Please send success and failure reports with "./config.guess" output to <m...@loria.fr>. If no problems are found, GNU MPFR 2.4.2 should be released around 2009-11-30.
