[Rd] path to rtools not updated in R 4.2.3 - line 1: gcc: command not found

[Patrick Giraudoux]

Dear listers,

I have update to rtools43 and, using R 4.2.3 I have been surprised not 
to be able to compile packages needing compilation when updating.

Looks like the path given in

gcc  -I"C:/PROGRA~1/R/R-42~1.3/include" -DNDEBUG -DNTIMER 
-I./SuiteSparse_config -DUSE_FC_LEN_T 
-I"C:/rtools42/x86_64-w64-mingw32.static.posix/include"     -O2 -Wall  
-std=gnu99 -mfpmath=sse -msse2 -mstackrealign  -c CHMfactor.c -o CHMfactor.o
/bin/sh: line 1: gcc: command not found

points to rtools42 by defaut

I have fixed the issue changing the folder name rtools43 into rtools42, 
but I wonder wether this is recommandable...
