[Mesa-dev] [PATCH 7/9] mapi/glapi: Fix dll linkage of GLES1 symbols.

[jfonseca at vmware.com]

From: José Fonseca <jfonseca at vmware.com>

This fixes several MSVC warnings like:

  warning C4273: 'glClearColorx' : inconsistent dll linkage

In fact, we should avoid using `declspec(dllexport)` altogether, and use
exclusively the .DEF instead, which gives more precise control of which
symbols must be exported, but all the public GL/GLES headers practically
force us to pick between `declspec(dllexport)` or
`ideclspec(dllimport)`.
