14 | Note this is a *build* target (in build-x86_64-linux) so it should be using | ||
15 | the host "gcc", not x86_64-pokysdk-mingw32-gcc. Since the mingw32 headers are | ||
16 | very different, using the wrong cpp is a real problem. It is leaking into | ||
17 | configure through the CPP variable. Ultimately this leads to build failures | ||
18 | related to not being able to include a process.h file for pem-unix.c. | ||
19 | |||
20 | The fix is to ensure we export a sane CPP value into the build environment when | ||
21 | using build targets. We could define a CPP_FOR_BUILD value which may be the version | ||
22 | which needs to be upstreamed but for now, this fix is good enough to avoid the | ||
23 | problem. | ||
