748217 - undefined references to _InterlockedIncrement and family

Status: NEW

(NSPR :: NSPR, defect)

Description

[Robert]

Attachment: use system header if available

Issue:
- when cross compiling for mingw32 on Fedora16, I get undefined references
  for the _Interlocked* functions declared in pr/include/pratom.h.
- there are versions of these functions, without the '_' prefix,
  declared in winbase.h for both the fedora cross-compile and
  MozBuild environments.

Fix
- add a configure check for winbase.h and windows.h
- modify pr/include/pratom.h. IFF configure found windows.h,
  winbase.h AND winbase hasn't already been included, then
  include windows.h and winbase.h, and use the non-prefixed
  version of the Interlocked* functions declared in winbase.h
  for all the PR_ATOMIC_* macros

I know that cross compiling isn't officially supported, but it just makes more sense to me to use system headers for prototype when available.
