216 | 21 [*] added support for compiling using MinGW and added portions of gnulib |
22 to support argp, among other things. Yah! A Windows build! | |
187 | 23 [+] added library search path (-L) and library specification (-l) to LWLINK |
24 [+] added ability to specify section base addresses on the command line to | |

188 | 28 [+] added ability to extract files in LWAR |
29 [+] added ability to "replace" members in LWAR | |
