PR modula2/109496 Fix constant char parameter passing to an array of char
This patch fixes PR modula2/109496 and PR modula2/109497. The fix for
PR modula2/109496 promotes a char constant to a string. The PR
modula2/109497 allows for constant chars to be added to form a string.
The fixes for both PR's occur in M2GenGCC.mod and M2GCCDeclare.mod
after the resolving of constant declarations.
gcc/m2/ChangeLog:
* gm2-compiler/M2ALU.def (PopChar): New procedure function.
* gm2-compiler/M2ALU.mod (PopChar): New procedure function.
* gm2-compiler/M2GCCDeclare.mod (PromoteToString): Detect
a single constant char and build a C string.
* gm2-compiler/M2GenGCC.mod (IsConstStr): New procedure
function.
