1# Project: gvimext
2# Generates gvimext.dll with gcc.
3# To be used with MingW and Cygwin.
4#
5# Originally, the DLL base address was fixed: -Wl,--image-base=0x1C000000
6# Now it is allocated dymanically by the linker by evaluating all DLLs
7# already loaded in memory. The binary image contains as well information
8# for automatic pseudo-rebasing, if needed by the system. ALV 2004-02-29

13# For the old MinGW 2.95 (the one you get e.g. with debian woody)
14# set the following variable to yes and check if the executables are
15# really named that way.

17# check also the executables
