Convert Object and Lib Files to OMF
Digital Mars tools all work with the Intel 32 bit OMF object and library file format. Microsoft's 32 bit tools work with Microsoft's own variant of the COFF format. Many such COFF format files can be converted to OMF with the coff2omf program: 
        coff2omf inputfiles...

  -h, -?  Display help
  -q      Quiet mode
  -v      Verbose mode
  -r      Remove (delete) output file if empty
  -lib:xx Specify options for OMF import library generation:
       ms - Allow entries that have MS C++ name mangling (default: no)
       st - Normalize names instead of aliasing MS stdcall mangling
       ca - Don't perform MS cdecl aliasing (default is to alias)    COFF2OMF will convert a COFF import library file (InputFile)
to the corresponding OMF type import library file (OutputFile).            
The input files can be either object files (.obj) or library files (.lib). They are converted in place to OMF. 
For example, to convert user32.lib from COFF to OMF:             COFF2OMF input.lib output.lib
        
The Microsoft COFF format apparently changed with Visual C++ 6.0. To use coff2omf on a .lib file with the newer format, use Microsoft's linker to convert the file to the earlier COFF format: 
        link /lib /convert file.lib
        
and then use coff2omf on it.

hcw 你好:
(1)據我所知是不行的，因為 *.lib(Win32 Static Library) 在 VC 及 BCB 中
   的格式是不相同的，至於有沒有現成的工具可以轉換?? 這點我就不太清楚了
(2)小弟我一般的做法，是先用 VC 把原來的 *.lib 包成 Win32 DLL 再給 BCB
   使用(靜態連結或動態連結)，這種方式是肯定沒問題的
