[Plplot-devel] [PATCH] drivers/wingdi: Fix compiling in 64-bit Windows system

[Biswapriyo N. <nat...@gm...>]

This replaces GCL_HCURSOR with GCLP_HCURSOR because the previous one
is undefined in 64-bit Windows SDK and in mingw-w64 toolchain. Hence,
fixes the following compiler error.

plplot/drivers/wingdi.c: In function 'CrossHairCursor':
plplot/drivers/wingdi.c:201:33: error: 'GCL_HCURSOR' undeclared (first use in this function); did you mean 'GCLP_HCURSOR'?
  201 |     SetClassLongPtr( dev->plot, GCL_HCURSOR, (long) cursor );
      |                                 ^~~~~~~~~~~
      |                                 GCLP_HCURSOR
