但在 release 版本里,他们做了小小的改变,在 release notes 里说得很清楚了
Traditionally, applications that use InterBase or Firebird have expected to load the gds32.dll client
library from the <system> directory. Firebird 1.5 ships a tool named 'instclient.exe' that can install a
clone of fbclient.dll to the Windows System directory. This clone gets patched on the fly so that its file
version information begins with "6.3", to provide compatibility for old applications that check the
GDS32.DLL file version and can not make sense of a number string such as "1.5".
