Comment (by robe):

 Okay tested on my mingw setup (my setup is old BTW gcc 8.1 but that is
 another story)

 At anyrate the patch seems to screw up ability to find CC.

 Looking at the postgis/Makefile generated, it seems to have


 {{{
 CUSTOM_CC := $(CC)
 }}}

 Which I am assuming is the culprit.  By comparison, the generated
 liblwgeom/Makefile has


 {{{
 CC = x86_64-w64-mingw32-gcc
 }}}

 trying to change Makefile.in to below gets me back to the original error

 {{{
 CUSTOM_CC := @CC@
 }}}

 FWIW I think @strk was saying we should get rid of PGXS as it's causing
 more issues than helping.
