[gambit-list] building git master fails

trying to build the master branch from githug fails

I followed the steps from INSTALL.txt section 1 §2 (wget ...gambit-4_9_3-devel.tar.gz et.c) followed

./configure --enable-single-host --prefix=~/test

make

make bootstrap

git pull

make realclean

# again: ./configure --enable-single-host --prefix=~/test

make

----

The resulting ___CHARALPHABETICP being undefined I solved by adding a line to config.h.in:

#define ___USE_C_RTS_CHAR_OPERATIONS

But the "Ill-placed 'declare'" in _num.scm line 5525 is above my head. Looks an issue with `define-prim&proc` -- but I don't understand it.

Any help appreciated.

best
