Now they work on MinGW and Cygwin as well. + +1.4.1 (21 November 2007) +* Fixed memory leak in ginac_yylex(). +* Fixed memory leaks in mul::eval() and power::eval(). +* Fixed macro checking for version of libreadline (Mac OS X). +* Fixed broken preprocessor instruction in excompiler.cpp. +* Fixed broken module loading in excompiler.cpp. +* info(info_flags::has_indices) now works for sums and products. +* Improved mul::expand(). +* Improved CLN output. 1.4.0 (31 August 2007) * New tinfo mechanism. -- 2.44.0
